Abstract
A write buffer having selective flush is disclosed. The write buffer has address buffers and associated data buffers and comparators. During a 'sneak read' operation, the address of the read operation is compared to the address signals stored in each of the address buffers. If a match is found, the read operation is temporarily suspended for only as long as the matched address remains stored in the write buffer. In a further improvement, the overhead associated with each match can be minimized to one write operation for each match before the matched address and data signals are written out of the write buffer.
