Abstract: A system having a split bus flash memory and a method for operating the split bus flash memory is disclosed. The system may include a controller, a non-volatile memory (including first and second non-volatile memory chips) and the system bus. The controller is configured to communicate via an N-bit bus. The first and second non-volatile memory chips are configured to communicate via an M-bit bus, with M<N. The system bus connects the controller with the first and second non-volatile memory chips, wherein the system bus is split with some of the system bus lines connected to the first non-volatile memory chip and other of the system bus lines connected to the second non-volatile memory chip. In this way, the controller may communicate command, address and/or data with the memory chips in parallel.

Abstract: A server system, such as an enterprise server, may include an array of memory devices. The memory devices may include non-volatile or flash memory and be referred to as flash storage modules (“FSM”). The server system includes a host computer or host server that communicates with the array of FSM. The host may include a media management layer or flash transformation layer that is implemented by drivers on the host for controlling the FSM.
