Abstract
A bit line sense amplifier overdriving method includes a step for reaching a bit line data signal to a full swing level by driving the sense amplifiers in accordance with an overdriving voltage in an overdriving pulse interval, when an overdriving pulse signal is generated at points in which the sense amplifiers are enabled and disabled in a data read operation and a data write operation. The method maintains a sufficiently long refresh interval during a refresh operation.
Claims6
A method of overdriving a bit line of a memory device during one of reading and writing operations, the method comprising the steps of:
- activating a word line of the memory device;
- enabling a sense amplifier;
- applying a first overdrive signal of a first prescribed pulse width to a sense amplifier driver when the sense amplifier is enabled;
- disabling the sense amplifier;
- applying a second overdrive signal of a second prescribed pulse width to the sense amplifier driver when the sense amplifier is disabled, wherein the bit line is overdriven to a full swing level during application of the first and second overdrive signals.
