INTEGRATED CIRCUIT DEVICE, READ DATA AMPLIFIER, AND METHOD FOR OPERATING READ DATA AMPLIFIER

摘要

PROBLEM TO BE SOLVED: To provide a read data amplifier optimized for the output data path of integrated circuit memory arrays including a fast, low power and small on-chip area consuming circuit which is advantageously effectuated through the combined application of "current sensing" and "voltage sensing" techniques. SOLUTION: An amplifier enable signal is timed with the column read address so that the amplifier is turned "off" when not in use and both data read lines ("DR" and "DRB") are precharged "high". No clocking of the read data amplifier is required in order to obviate undesired clock latency and pipelining, and a simple mechanism is realized such that control of power-up and power-down results in further power savings.
