Abstract
A memory includes an ROM portion storing information specific to the memory, and transfers the stored information to a memory controller via an output buffer and a sink link. The memory controller manages the characteristics of the memory, so that a memory system can be structured utilizing memories of different characteristics.
Claims10
A semiconductor memory device operating according to a command supplied via a first bus, comprising:
- store means for storing specific information inherent in said semiconductor memory device;
- and
- output means for sending the specific information stored in said store means onto a second bus according to a transfer command supplied via said first bus.
A memory system comprising:
- a memory controller;
- and
- a plurality of semiconductor memory devices connected in parallel with each other to said memory controller via first and second buses respectively transferring information in one direction, and operating according to a command transmitted via said first bus from said memory controller, wherein
- each of said semiconductor memory devices includes
- store means for storing specific information inherent in said semiconductor memory device, and
- output means for transferring the specific information stored in said store means to said memory controller via said second bus, according to a transfer command supplied from said memory controller via said first bus.
