Multi-bank memory with interleaved or parallel accesses of banks

摘要

A micro-threaded memory device. A plurality of storage banks are provided, each including a plurality of rows of storage cells and having an access restriction in that at least a minimum access time interval must transpire between successive accesses to a given row of the storage cells. The memory device has a mode of operation in which a first column access request is directed to a first open row in a first one of the storage banks and a third column access request is directed to a second open row in a second one of the storage banks, the receipt of the third column access request can correctly occur before the minimum access time interval has elapsed since the receipt of the first column access request.
