摘要
Power-on-reset (POR) circuits for resetting memory devices, and related circuits, systems, and methods are disclosed. In one embodiment, a POR circuit is provided. The POR circuit is configured to receive as input, a plurality of decoded address outputs from at least one memory decoding device. The POR circuit is further configured to generate a POR reset if any of the plurality of decoded address outputs are active. As a result, memory decoding device latches can be reset to a known, default condition to avoid causing an unintentional word line selection in the memory during power-on state before an external reset is available. Because the POR circuit can generate the POR reset without need of an external reset, the memory decoding devices can be reset quickly to allow for quicker availability of memory after a power-on condition.
