High-speed, low-power, current mirrored sense amplifier

摘要

The present invention relates to a high-speed, low-current current mirror sense amplifier. In a general sense amplifier, when a high-speed process is required, the sizes of the sensing transistor and the enable transistor must be increased. In this case, There is a defect that the size of the device must be increased. In order to solve this problem, in order to solve this problem, the sense amplifier is binarized to compare the output state of the sense amplifier, The sensing speed is improved. When the sensing operation is sufficiently advanced and the outputs are generated as "low" and "high", only some of the sense amplifiers are enabled to maintain the output of the sense amplifiers.
