Abstract:
A synchronous Flash memory device is described that enhances initialization and boot memory device identification in synchronous memory systems. A boot memory is typically a separate device that is tied to a specific chip select line and/or address range of a system, whereas synchronous Flash memory generally can be placed in any available memory slot and assigned one of several possible chip selects and address ranges. This lack of predictability makes installing a boot memory based on a non-volatile synchronous memory device difficult. A synchronous Flash boot memory device of the detailed invention is adapted to identify itself and its chip select/address range to the memory controller at power up, reset, or upon receiving an identification request. This allows the utilization of the detailed synchronous Flash memory as a boot memory in synchronous systems where a reserved boot memory slot and/or chip select are not provided.
