ABSTRACT:
A flash memory controller operates a flash memory array comprising a plurality of different types of flash memory chips. The CPU interacts with the array by issuing generic commands through a single Memory Technology Driver (MTD), while the controller translates the generic commands into commands specific to the chip comprising the portion of the array being addressed. The controller operates each of the flash chips which comprises the flash memory array, and presents to the CPU a memory system comprised of a single addressable entity. According to a further feature of the invention, the controller is embedded into each of the flash chips in an array in order to further reduce overhead costs.
