Description

ABSTRACT:
A memory interface unit capable of coupling a microprocessor to memory external to the microprocessor, wherein the memory can be of at least two types differing in width, and where the data stored in such memory can be in different sizes, and wherein the memory can be formed in sections. The invention utilizes means for controlling at least two strobe signal lines and means for shifting the memory address lines, programmably, so as to accommodate the various combinations of memory width and data size.
