High capacity dimm memory with data and state memory

摘要

A dual in-line memory module (DIMM) including a circuit board and a plurality of semiconductor memory chips mounted on the circuit board, the memory chips providing 128 Megabytes of data storage on the DIMM. The memory chips are logically organized into first and second memory bank portions which are separately addressable. The first memory bank portion is logically organized into memory blocks for storing data, and the second memory bank portion is configured to store directory information for the memory blocks of the first memory bank portion.
