Retention optimized memory device using predictive data inversion
View Patent ↗A method for storing data. The method includes providing an addressable memory including a memory space, wherein the memory space includes a plurality of memory cells. The method includes configuring the addressable memory such that a majority of the plurality of memory cells in the memory space stores internal data values in a preferred bias condition when a first external data state of one or more external data states is written to the memory space, wherein the first external data state is opposite the preferred bias condition.
1. A method comprising,
providing an addressable memory comprising a memory space;
configuring said addressable memory such that a majority of a plurality of memory cells in said memory space stores internal data values in a preferred bias condition when a first external data state of one or more external data states is written to said memory space, wherein said first external data state is opposite said preferred bias condition;
when an address of a memory cell to be written is coupled to a bit line that is further coupled to a positive side of a sense amplifier, inverting a data input value of a data in signal to generate an inverted data input value; and
delivering said inverted data input value to said positive side.
