FLASH MEMORY CONTROLLER CONTROLLING VARIOUS FLASH MEMORY CELLS |
摘要 |
An electronic data flash card is accessible by a host system, and includes a flash memory controller and at least one flash memory device coupled to the flash controller. The boot code and control code for the flash memory system (flash card) are stored in the flash memory device during a programming procedure. The flash controller transfers the boot code and control code to a volatile main memory (e.g., random access memory or RAM) at start up or reset making a RAM-based memory system. Boot code and control code are selectively overwritten during a code updating operation. A single flash controller thus supports multiple brands and types of flash memory to eliminate stocking issues.
