Abstract
A dynamic random access memory (DRAM) includes priority access control circuitry, where the DRAM has a first precharge mode and a priority precharge mode. In the first precharge mode, the array is precharged during an external row address strobe (RAS) and accessed during an active state of the external RAS. In the priority precharge mode, the array is precharged during a precharge state of an internal RAS initiated by a priority signal received during any one of the precharge and active states of the external RAS, where the priority access control circuitry returns to the first mode on a subsequent precharge state of the external RAS.
