Abstract:
A memory system that reduces the memory cycle time of a memory cell by performing an incomplete write operation. The voltage on a storage node of the memory cell does not reach a full supply voltage during the incomplete write operation. The incomplete write operation is subsequently completed by one or more additional accesses, wherein the voltage on the storage node is pulled to a full supply voltage. The incomplete write operation may be completed by: subsequently writing the same data to the memory cell during an idle cycle; subsequently writing data to other memory cells in the same row as the memory cell; subsequently reading data from the row that includes the memory cell; or refreshing the row that includes the memory cell during an idle cycle. One or more idle cycles may be forced to cause the incomplete write operation to be completed in a timely manner.
