Abstract
A circuit includes a memory array having a plurality of memory cells; a control logic circuit, coupled to the memory array, and configured to use a first voltage signal to cause a first memory cell of the plurality of memory cells to transition from a first resistance state to a second resistance state, and a second voltage signal to cause the first memory cell to transition from the second resistance state to a third resistance state; and a counter circuit, coupled to the control logic circuit, and configured to increment a count by one in response to the first memory cell's transition from the first to the second resistance state, and again increment the count by one in response to the first memory cell's transition from the second to the third resistance state.
