Abstract:
Methods, systems, and devices related to counter-based sense amplifier method for memory cells are described. The counter-based read algorithm may comprise the following phases:
storing in a counter associated to an array of memory cells the value of the number of bits having a predetermined logic value of the data bits stored in the memory array;
reading from said counter the value corresponding to the number of bits having the predetermined logic value;
reading the data stored in the array of memory cells by applying a ramp of biasing voltages;
counting the number of bits having the predetermined logic value during the data reading phase;
stopping the data reading phase when the number of bits having the predetermined logic value is equal to the value stored in said counter.
