HIGH SPEED MEMORY SYSTEM CAPABLE OF SELECTIVELY OPERATING IN NON-CHIP-KILL AND CHIP-KILL MODES

摘要

The present invention provides a high data bandwidth memory system capable of operating in nonchipkill (101) and chipkill (110) modes. In chipkill mode (110), cycle multiplexing, bit multiplexing, and time and space multiplexing are used to read/write data and syndrome across a group of memory devices (112). Current command packet formats are adapted to communicate with the group of memory devices in chipkill mode (110).
