Memory module and control method of serial peripheral interface using address cache
A serial peripheral interface memory module using address cache comprises a flash memory array for storing data, a serial/parallel convertor for receiving serial signals and generating a control command, an address and data, an address register, an address accumulator for accumulating the address in the address register and storing the accumulated address back to the address register, and a flash memory controller for controlling the access to the flash memory array. When the control command is a standard command, the serial/parallel controller first stores the address following the control command into the address register and then the flash memory controller accesses data according to the address in the address register. When the control command is a specific command, the flash memory controller directly accesses data according to the address in the address register without waiting for an address update.
