Abstract: A sensing module, a memory device, and a sensing method are provided to perform a read operation so that the un-programmed/programmed state of a memory cell is identified. The sensing module includes a sensing amplifier and a current sink, and both are electrically connected to the memory cell. The sensing amplifier generates a sensing current and identifies the un-programmed/programmed state of the memory cell accordingly. The current sink receives a reference current being equivalent to the summation of the sensing current and a cell current flowing through the memory cell. The reference current is constant, and the sensing current is changed with the cell current. The cell current is generated based on a high read voltage and a low read voltage applied to the memory cell. The sensing current is higher if the memory cell is un-programmed, and the sensing current is lower if the memory cell is programmed.

Abstract: A method and system is disclosed for creating a timing delay for power-on reset. A state machine is formed with three states. It resets a counter value to a predetermined number in an initial state, and increments the counter value for a predetermined number of reset cycles in a reset state until the counter value reaches a predetermined value for creating the time delay, and ends the reset state in a finish state if the counter reaches the predetermined value and if a randomly generated value matches a predetermined signature, wherein if in the reset state the randomly generated value does not match the signature or if in the finish state either the counter value does not reach the predetermined value or the randomly generated value does not match the signature, the initial state starts and subsequently enters the reset state after resetting the counter value.
