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%
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.
Intel has terminated its Optane line of memory. Sold its NAND flash memory and SSD businesses to SK Hynix. Intel has terminated its Optane line of SSDs. No Sold its NAND flash memory and SSD businesses to SK Hynix, so SK Hynix now makes those controllers. Intel has also terminated its Optane controller business. Kaminario [14] United States No ...
On September 17, 2007, Texas Memory Systems (TMS) announced the RamSan-500, the world's first enterprise-class flash-based solid state disk (SSD). [2] 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 ...
In computer storage, a disk buffer (often ambiguously called a disk cache or a cache buffer) is the embedded memory in a hard disk drive (HDD) or solid-state drive (SSD) acting as a buffer between the rest of the computer and the physical hard disk platter or flash memory that is used for storage.

File Systems for Open-Channel SSDs With open-channel SSDs, the L2P mapping can be directly integrated or merged with storage management in file systems. [10] This avoids the redundancy between system software and SSD firmware, and thus improves performance and endurance. Further, open-channel SSDs enables more flexible control over flash memory.
A flash memory storage system with no wear leveling will not last very long if data is written to the flash. Without wear leveling, the underlying flash controller must permanently assign the logical addresses from the operating system (OS) to the physical addresses of the flash memory. This means that every write to a previously written block ...
In practice, flash file systems are used only for Memory Technology Devices (MTDs), which are embedded flash memories that do not have a controller. Removable flash memory cards and USB flash drives have built-in controllers to manage MTD with dedicated algorithms, [2] [3] like wear leveling, bad block recovery, power loss recovery, garbage ...
