Abstract
A high memory capacity DIMM for use in a directory-based, distributed shared memory multiprocessor computer system includes a data memory for storing data and a state memory for storing state or directory information corresponding to at least a portion of the data. The DIMM allows the data and the state information to be accessed independently. The DIMM is configured for use in a DIMM pair. In the DIMM pair, a first DIMM includes a first data memory having first and second memory bank portions for storing data, and a first state memory configured to store state information corresponding to data stored in a first memory bank. A second DIMM includes a second data memory having third and fourth memory bank portions for storing data, and a second state memory configured to store state information corresponding to data stored in a second memory bank. The first memory bank is formed from the first memory bank portion and the third memory bank portion. The second memory bank is formed from the second memory bank portion and the fourth memory bank portion.
