ABSTRACT:
A computer includes a processor for processing data, and memory modules for storing the data. Each memory module includes a read-write memory and a configuration memory. The configuration memory (i) contains memory module characteristic information, (ii) is adapted for storing a sequence of binary data values, accessing the stored binary data only in sequential order, and only at the first data value or the next data value, and (iii) has a NEXT signal pin. The configuration memory is adapted for receiving at the NEXT signal pin, and responding to, a CAS signal used by standard DRAMs. In other features of the invention, the memory module characteristic information includes an identification code for the manufacturer of the memory module, a part number for the memory module, the depth of the memory, access times to read full and page, and delay times to read and write full and page.
