Abstract
A method includes storing data in an analog memory cell by writing an analog value into the memory cell. After storing the data, the data stored in the memory cell is read by discharging electrical current to flow through the memory cell, during a predefined time interval, while applying a variable voltage to a gate of the memory cell. A fraction of the predefined time interval, during which the variable voltage allows the electrical current to flow through the memory cell, is estimated. The stored data is estimated based on the estimated fraction.
