Abstract
A memory access system and method is provided to modify a memory interleaving scheme so that data can be read from a memory system in any sequence without inserting a waiting cycle. Even addressees are assigned to a first memory bank and odd addresses to a second memory bank. If a sequential address sequence is being provided, the first and second memory banks are read alternately. A third memory bank is provided which has the contents of both first and second memory banks. When an address sequence is detected that successively accesses either the first memory bank or the second memory bank, the access is switched to the third memory bank.
