Abstract

The present invention provides a look ahead architecture to satisfy the retransmit recovery time constraints in a mark and retransmit system while allowing a full bitline precharge. A number of sense amplifiers are provided in the look ahead architecture that may be equipped with a "shadow latch" to store the read data when the mark pointer is asserted. As a result, the data to be retransmitted will be retrieved from the shadow latches when the retransmit is asserted, allowing a full precharge cycle before reading from the memory array.
