ABSTRACT:
In a sense amplifier and method of generating a variable reference level, the sense amplifier varies a reference voltage level in accordance with variation of a operating voltage. This ensures that on-cell and off-cell margins required to detect data are sufficiently maintained regardless of the variation of the operating voltage in the semiconductor memory device. Read failures that otherwise would be generated due to insufficient voltage sensing margin are thus avoided.
