Semiconductor memory device with sense amplifier that operates for two different voltage range and writing method thereof

Abstract

A semiconductor memory device and a writing method thereof. The semiconductor memory device includes a memory control circuit and a memory array. The memory array includes a target memory bank. The target memory bank includes a target memory cell and a sense amplifier circuit. The sense amplifier circuit is coupled to the target memory cell via a bit line, receives a data signal within a first voltage value range from the memory control circuit, and generates a bit line signal within a second voltage value range on the bit line according to the data signal. The second voltage value range is greater than the first voltage value range.
