Patent ID: 7068562

Claim:
A memory module mounted in a package, comprising: a non-volatile memory; a random access memory; a controller controlling the non-volatile memory and the random access memory; a controller controlling the non-volatile memory and the random access memory; a command register written an instruction code; a plurality of external command signal terminals; a plurality of external address terminals; and a plurality of external data terminals, wherein the controller reads out data from the non-volatile memory and writes the data read out from the non-volatile memory to the random access memory when a load instruction code is written into the command register, wherein when command signals inputted to the plurality of command signal terminals indicate a write operation and address signal inputted to the plurality of external address terminals indicate an access to the command register, the load instruction code is written into the command register via the plurality of external data terminals, and when command signals inputted the plurality of command signal terminals indicate the write operation and address signal inputted to the plurality of external address terminals indicates an access to the random access memory, data inputted to the plurality of external data terminals is written into the random access memory.
