MS7AA Memory Technical Manual

This technical manual describes the MS7AA memory module, designed for computer systems built around the LSB bus, providing incremental storage capacities ranging from 64 Mbytes to 2 Gbytes.

The document details the module's architecture, including its Memory Interface Controller (MIC), Memory Data Controller (MDC), and DRAM arrays. Key functionalities include memory organization (banking and interleaving for enhanced performance), data transfer mechanisms like 64-byte block transfers and data wrapping, and robust error correction using Quadword ECC (for DRAM) and Longword ECC (for LSB) with conversion logic.

The manual also covers LSB memory signals, various read/write memory transactions, error conditions, and comprehensive descriptions of registers used for configuration, status, and error reporting, as well as self-test procedures and performance. It is intended for developers of system and application software with machine-level programming knowledge.
