When the system or device needs to read data from or write data to the flash memory, it will communicate with the flash memory controller. Simpler devices like SD cards and USB flash drives typically have a small number of flash memory die connected simultaneously. Operations are limited to the speed of the individual flash memory die.
The following were the largest NAND flash memory manufacturers, as of the second quarter of 2023. [26] Samsung Electronics – 31.4%; Kioxia – 20.6%; Western Digital Corporation – 12.6%; SK Hynix – 18.5%; Micron Technology – 12.3%
The Flash Modules were designed from the ground up by Texas Memory Systems using proprietary form-factors, physical connectivity, hard-decision ECC algorithm, and flash translation layer (FTL) contained completely inside the SSD. The flash controllers used a hardware only data path that enabled lower latency than any other commodity controllers ...
The first details of a new standard for accessing non-volatile memory emerged at the Intel Developer Forum 2007, when NVMHCI was shown as the host-side protocol of a proposed architectural design that had Open NAND Flash Interface Working Group (ONFI) on the memory (flash) chips side. [26] A NVMHCI working group led by Intel was formed that year.
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 ...
As SSD technology continues to improve, they are increasingly used in ultra-mobile PCs and lightweight laptop systems. The first flash-memory SSD based PC to become available was the Sony Vaio UX90, announced for pre-order on 27 June 2006 and began shipping in Japan on 3 July 2006 with a 16 GB flash memory hard drive.

An illustration of the write amplification phenomenon in flash-based storage devices. Over time, advancements in central processing unit (CPU) speed has driven innovation in secondary storage technology. [7] One such innovation, flash memory, is a non-volatile storage medium that can be electrically erased and reprogrammed.
Phison SSD controller. Phison Electronics Corporation (Chinese: 群聯電子; pinyin: Qúnlián Diànzǐ) is a Taiwanese public electronics company that primarily designs, manufactures and sells controllers for NAND flash memory chips. [1] These are integrated into flash-based products such as USB flash drives, memory cards, and solid-state ...
