Abstract
An address device simultaneously provides a first address to a first memory section using a first address bus and a second, incrementally higher, address to a second memory section using a second address bus. A buffer can then read from or write to the first and second memory sections. During a read operation, the buffer can receive a first portion of a misaligned data word from the first memory section and read a second portion of the misaligned data word from the second memory section and assemble the data in the data word from the first and second portions. When the access operation is a write operation, the buffer can effectively perform a shift operation on the data in the data word, then write a first portion of the word to the first memory section and write a second portion of the word to the second memory section. Accordingly, data accesses that would take two memory-access cycles on a conventional memory system are reduced to a single memory-access cycle.
