Self-adaptive sensing design

Abstract

The invention discloses a self-adaptive sensing design. A clock signal having a clock pulse width duration is received. A delay time is received. A first relationship and a second relationship between the clock pulse width duration and the delay time are determined. A new clock is generated that has a first new clock pulse width duration determined by the first relationship and the delay time and a second new clock pulse width duration determined by the second relationship and the clock pulse width duration. Switching between the first new clock pulse width duration and the second new clock pulse width duration is automatic based on the first relationship and the second relationship.

Description

technical field [0001] The present disclosure relates to adaptive sensing design. Background technique [0002] Sensing circuits generally have two modes: self-timed mode and clock-based mode. In the self-timing mode, a reference clock (eg, clock CLK) edge (eg, rising edge) generates a pulse width of a word line (eg, word line WL) based on a delay time. For example, the rising edge of word line WL is generated after a time delay of TWLR from the rising edge of clock CLK at time TCLKR, and the falling edge of word line WL is generated after a time delay of TWLF from time TCLKR. Actually, word line WL has a pulse width of duration TWLF-TWLR. [0003] Similarly, the rising edge of the signal SAE is generated from the time TCLKR after a delay time TSAER, and the falling edge of the signal SAE is generated from the time TCLKR after a delay time TSEAF. As a result, signal SAE has a pulse width of duration TSAEF-TSAER. In other words, the rising edge and falling edge of the wor...

[0005] In some methods using self-timed and clock-based modes, a manual switch is used to switch between self-timed and clock-based modes, which becomes complicated and requires human intervention
