Abstract
An integrated circuit including a sense amplifier connected to a sense line is provided. The sense amplifier is configured to end a precharge phase of the sense line based on a state of the sense amplifier. A single-ended sense amplifier determines its own precharge level, ends the precharge phase, and starts evaluation as soon as precharge is ended, without waiting for a globally timed signal to end the precharge phase.
Claims20
A method of manufacturing an integrated circuit, comprising:
- forming a single-ended sense amplifier connected to a sense line, wherein the sense amplifier is configured to end a precharge phase of the sense line based on a state of the sense amplifier.
An integrated circuit, comprising:
- a sense amplifier connected to a sense line, wherein the sense amplifier is configured to end a precharge phase of the sense line based on a signal that is generated internally within the sense amplifier.
A method of evaluating a sense line in an integrated circuit, comprising:
- receiving a start signal at a sense amplifier, wherein the start signal is generated externally to the sense amplifier;
- beginning a precharge phase of the sense line based on the receiving the start signal;
- and
- ending the precharge phase and beginning an evaluation phase based on a signal that is generated internally within the sense amplifier.
