The pages are typically 512, [98] 2,048 or 4,096 bytes in size. Associated with each page are a few bytes (typically 1/32 of the data size) that can be used for storage of an error correcting code (ECC) checksum . Typical block sizes include: 32 pages of 512+16 bytes each for a block size (effective) of 16 KiB. Ver mais 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 Ver mais Block erasure One limitation of flash memory is that it can be erased only a block at a time. This generally sets all bits in the block to 1. Starting with a freshly erased block, any location within that block can be programmed. … Ver mais NOR and NAND flash differ in two important ways: • The connections of the individual memory cells are different. • The interface provided for reading and writing the memory is different; NOR allows random access, while NAND allows … Ver mais Background The origins of flash memory can be traced back to the development of the floating-gate MOSFET (FGMOS) Ver mais Flash memory stores information in an array of memory cells made from floating-gate transistors.
