Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR and NAND logic gates. Both use the same cell design, consisting of floating gate MOSFETs. They differ at the circuit level depending on whether the state of the bit line or word lines is pulled high or low: in NAND flash, the relationship between the bit line and the word lines resembles a NAND gate; in NOR flash, it resembles a NOR gate.
Atmel Corporation was a creator and manufacturer of semiconductors before being subsumed by Microchip Technology in 2016. Atmel was founded in 1984. The company focused on embedded systems built around microcontrollers. Its products included microcontrollers radio-frequency (RF) devices including Wi-Fi, EEPROM, and flash memory devices, symmetric and asymmetric security chips, touch sensors and controllers, and application-specific products. Atmel supplies its devices as standard products, application-specific integrated circuits (ASICs), or application-specific standard product (ASSPs) depending on the requirements of its customers.
Western Digital Corporation is an American computer drive manufacturer and data storage company, headquartered in San Jose, California. It designs, manufactures and sells data technology products, including data storage devices, data center systems and cloud storage services.
Wear leveling is a technique for prolonging the service life of some kinds of erasable computer storage media, such as flash memory, which is used in solid-state drives (SSDs) and USB flash drives, and phase-change memory. There are several wear leveling mechanisms that provide varying levels of longevity enhancement in such memory systems.
MultiMediaCard, officially abbreviated as MMC, is a memory card standard used for solid-state storage. Unveiled in 1997 by SanDisk and Siemens, MMC is based on a surface-contact low pin-count serial interface using a single memory stack substrate assembly, and is therefore much smaller than earlier systems based on high pin-count parallel interfaces using traditional surface-mount assembly such as CompactFlash. Both products were initially introduced using SanDisk NOR-based flash technology.
Transcend Information, Inc. is a Taiwanese company headquartered in Taipei, Taiwan that manufactures and distributes memory products. Transcend deals in over 2,000 products including memory modules, flash memory cards, USB flash drives, portable hard drives, multimedia products, solid-state drives, dashcams, body cameras, personal cloud storage, card readers and accessories.

Its products include microcontrollers, Serial EEPROM devices, Serial SRAM devices, embedded security devices, radio frequency (RF) devices, thermal, power and battery management analog devices, as well as linear, interface and wireless products.
A solid-state drive (SSD) is a solid-state storage device. It provides persistent data storage using no moving parts. It is sometimes called semiconductor storage device or solid-state device; it is also called solid-state disk because it is frequently interfaced to a host system as a hard disk drive.
JMicron Technology Corporation is a Taiwan based fabless technology design house based in Hsinchu, Taiwan. As a manufacturer of integrated circuits, they produce controller chips for bridge devices.
Netlist Inc. is a Delaware-registered corporation headquartered in Irvine, California that designs and sells high-performance SSDs and modular memory subsystems to enterprise customers in diverse industries. It also manufactures a line of specialty and legacy memory products to storage customers, appliance customers, system builders and cloud and datacenter customers. Netlist holds a portfolio of patents in the areas of server memory, hybrid memory, storage class memory, rank multiplication and load reduction. Netlist has more than 120 employees and an annual revenue of US$142.4 million as of 2021 The stock was added to NASDAQ in late 2006. In the initial public offering of its common stock in 2006, Netlist sold 6,250,000 shares at $7.00 each. On September 26, 2018, Netlist announced they were moving from NASDAQ and currently trades on the OTCQB.
Bing Yeh is a Taiwanese-American electrical engineer and business executive.
ADATA Technology Co., Ltd. is a Taiwanese fabless hardware manufacturer, founded in May 2001 by Simon Chen. Its main product line consists of DRAM modules, USB flash drives, hard disk drives, solid state drives, memory cards and mobile accessories. ADATA is also expanding into new areas, including robotics and electric powertrain systems. In addition to its main ADATA brand, the company also sells PC gaming hardware and accessories under its XPG brand since 2008.
Solid-state storage (SSS) is non-volatile computer storage that has no moving parts – uses only electronic circuits. This solid-state design dramatically differs from the commonly-used competing technology of electromechanical magnetic storage which uses moving media coated with magnetic material. Generally, SSS is much faster but more expensive for the same amount of storage.
Virtium Solid State Storage and Memory is a privately held American company that manufactures semiconductor memory and solid-state disk (SSD) products for data storage in industrial/machine-to-machine designs, embedded systems, including small-footprint designs, and Industrial Internet of Things (IIoT) applications. The company's primary markets of focus include defense, industrial systems, network communications, and transportation. The name Virtium is derived from the word virtue.
ATP Electronics was a manufacturer of NAND based storage DRAM modules founded in Silicon Valley in 1991, headquarter was later moved to Taipei, Taiwan. ATP's product line consist of Industrial grade products, such as SSD, SD / microSD memory cards, along with DRAM products that are used in business industries across Networking, Enterprise Mobility, Automotive industry, Military, IPC/Embedded Systems, Health care, Gaming and The Internet of Things (IoT). Intel's CMTL, one of the largest third party testing lab for Intel server platforms, only recommended two memory modules companies to purchase motherboards in Taiwan, one noted to be ATP Electronics.
Silicon Motion Technology Corporation, stylized as SiliconMotion is an American-Taiwanese company involved in developing NAND flash controller integrated circuits (ICs) for solid-state storage devices. The company claims to have supplied more NAND flash controllers than any other company, over five billion from 2006 through 2016. They are found in commercial, enterprise, and industrial applications ranging from SSDs, eMMCs, memory cards, and USB flash drives.
In-situ processing also known as in-storage processing (ISP) is a computer science term that refers to processing data where it resides. In-situ means "situated in the original, natural, or existing place or position." An in-situ process processes data where it is stored, such as in solid-state drives (SSDs) or memory devices like NVDIMM, rather than sending the data to a computer's central processing unit (CPU).
IBM FlashCore Modules (FCM) are solid state technology computer data storage modules using PCI Express attachment and the NVMe command set. They are offered as an alternative to industry-standard 2.5" NVMe SSDs in selected arrays from the IBM FlashSystem family, with raw storage capacities of 4.8 TB, 9.6 TB, 19.2 TB and 38.4 TB. FlashCore modules support hardware self-encryption and real-time inline hardware data compression up to 115.2 TB address space, without performance impact.
