Abstract
Page mode memory access is enabled despite an immediately previous idle cycle. A row address strobe signal is maintained active during an idle cycle so that if a page hit is detected on a subsequent memory cycle, all that is needed to read or write to memory is a column address strobe signal which can be provided via a page mode access. In this manner, memory speed is enhanced because a conventional access is not required on the first memory cycle following one or more idle cycles.
