REFRESH CONTROL CIRCUIT, MEMORY, AND REFRESH CONTROL METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18157558 titled 'REFRESH CONTROL CIRCUIT, MEMORY, AND REFRESH CONTROL METHOD

Simplified Explanation

The patent application describes a refresh control circuit that includes three main components: a processing circuit, a logic circuit, and a power supply circuit.

  • The processing circuit receives a refresh command signal and performs pulse combination processing on it. The refresh command signal has a series of pulses in a first time period and maintains a constant level state in a second time period. These two time periods alternate.
  • The logic circuit receives the refresh command signal and the refresh combined signal from the processing circuit. It performs logical operation processing on these signals to obtain a target control signal.
  • The power supply circuit receives the target control signal and determines whether to perform a power supply operation based on the level state of the target control signal.


Original Abstract Submitted

A refresh control circuit includes: a processing circuit, configured to receive a refresh command signal, and perform pulse combination processing on the refresh command signal to obtain a refresh combined signal, the refresh command signal having a plurality of pulses in a first time period and keeping a level state unchanged in a second time period, and the first time period and the second time period existing alternately; a logic circuit, configured to receive the refresh command signal and the refresh combined signal, and perform logical operation processing on the refresh command signal and the refresh combined signal to obtain a target control signal; and a power supply circuit, configured to receive the target control signal, and determine whether to perform a power supply operation according to the level state of the target control signal.
