Serial flash Serial flash is a small, low-power flash memory that provides only serial access to the data - rather than addressing individual bytes, the user reads or writes large contiguous groups of bytes in the address space serially. Serial Peripheral Interface Bus (SPI) is a typical protocol for accessing the device. … See more 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 See more 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. … See more NOR and NAND flash differ in two important ways: • The connections of the individual memory cells are different. • The interface provided for reading and … See more Background The origins of flash memory can be traced back to the development of the floating-gate MOSFET (FGMOS), also known as the floating-gate … See more Flash memory stores information in an array of memory cells made from floating-gate transistors.
