In NAND flash memory, "blank" refers to a memory cell that has been erased and contains all 1s (binary value). This is the initial state of a NAND flash memory cell before data is programmed into it. When data is programmed into the cell, the 1s are changed to 0s, which can be read by the device accessing the memory.

in a nand flash, what's bank meaning?
In a NAND flash memory, a bank refers to a logical partition of the physical memory array. A bank is typically composed of several pages and blocks, and each bank can be accessed and programmed independently. The number of banks in a NAND flash memory varies based on the size and architecture of the memory device. Having multiple banks allows for more efficient utilization of the memory and enables faster read and write operations.
NAND FLASH 和NOR FLASH异同?
NAND Flash和NOR Flash都是非易失性存储器(Non-Volatile Memory),但它们有以下几个不同点:
1. 存储结构:NAND Flash采用串行存储结构,而NOR Flash采用并行存储结构。
2. 存储单元:NAND Flash的存储单元是页(Page),而NOR Flash的存储单元是字节(Byte)或字(Word)。
3. 读写速度:NAND Flash的读写速度比NOR Flash快。
4. 寿命:NAND Flash的寿命比NOR Flash长。
5. 价格:NAND Flash的价格比NOR Flash便宜。
总的来说,NAND Flash适合于大容量、高速度、低成本的存储应用,如固态硬盘(SSD),而NOR Flash适合于小容量、低速度、高可靠性的存储应用,如BIOS芯片。
