Patent ID: 6995596

Claim:
A method of generating a precharge pulse, comprising: initiating charging of the precharge pulse at a first edge of a first clock-like signal; and ending the charging of the precharge pulse after a time period that is longer of one of a preset delay period and a time period designated by a second edge of a second clock-like signal, wherein ending the charging of the precharge pulse after a time period that is longer of one of a preset delay period and a time period designated by a second edge of the second clock-like signal includes, transmitting the first clock-like signal to a first NAND gate; contemporaneously transmitting the second clock-like signal to a second NAND gate; transmitting an output of the second NAND gate to the first NAND gate and an inverter; and maintaining a charging state according to an output from the first NAND gate and the inverter.
