A method of operating a memory device includes placing the memory device
in a persistent auto precharge mode of operation, applying a disable
command to the memory device, and disabling the persistent auto precharge
mode of operation in response to the applied disable command. Memory
devices operating according this method may be used in memory systems
that infrequently experience page hits, such as server systems, while the
ability to disable the persistent auto precharge mode allows such memory
devices to be used in systems that frequently experience page hits, such
as graphics or input/output applications.
