Abstract
A memory system includes storage cells, a respective one of which is configured to store a fixed charge therein when a write voltage applied thereto is above a predetermined threshold voltage and to discharge the fixed charge therefrom when the write voltage applied thereto is below the threshold voltage. The storage cells may be charged and/or discharged at a latency that is a function of a voltage differential between the write voltage and the threshold voltage. A variable-latency write circuit for the storage cells is configured to dynamically vary the voltage differential between the write voltage and the threshold voltage to provide a variable-latency write operation that stores the fixed charge therein or discharges the fixed charge therefrom. Related methods are also discussed.
