Abstract
A memory device includes a sense amplifier circuit, a tri-state buffer, a data latch circuit and a data line. The sense amplifier circuit senses and amplifies a current of a memory cell. The tri-state buffer receives an output of the sense amplifier circuit. The data latch circuit latches an output of the tri-state buffer. The data line connects the tri-state buffer and the data latch circuit. The memory device removes charge on the data line using a latch enable signal, which is applied to the tri-state buffer before a read operation.
