ABSTRACT:
The various embodiments provide for programming floating-gate, or flash, memory devices by writing a block of data words to a volatile storage media from an external processor and programming the block of words to the nonvolatile flash memory cells from the volatile storage media without the need for further input from the external processor. In this manner, a block of words may be programmed into the flash memory device using a single write command and avoiding the need for a verify operation after programming each word. By utilizing an internal volatile storage media to receive the block of words prior to writing the individual words to the memory array, the external processor is free to perform other tasks while the programming and verification are performed autonomously by the memory device. Using an external power supply facilitates parallel transfer from the internal volatile storage media to the nonvolatile flash memory cells.
