Nand flash page buffer function
Witryna25 kwi 2024 · The page buffer and data cache serve as buffers between the memory array and the I/O circuit. Fast page-oriented data comparison in BIED flow is performed in page buffer. In this letter we assume the size of a page is 16K bytes as it is typical in dominant 3D NAND flash memory products. Witryna10 cze 2024 · 3D NAND Flash is the preferred storage medium for dense mass storage applications, including Solid State Drives and multimedia cards. Improving the latency of these systems is a mandatory task to narrow the gap between computing elements, such as CPUs and GPUs, and the storage environment. To this extent, relatively time …
