Voltage regulation method for dual-track memory, memory system and system on chip

Abstract

The invention provides a voltage regulation method for a dual-track memory, a memory system and a system on chip. The storage system comprises a dual-track memory comprising a logic device and a storage array; the voltage source is used for providing a first voltage signal and a second voltage signal for the logic device and the storage array; the clock source circuit is used for generating a clock signal of the double-track memory; the voltage difference detection unit is used for monitoring whether the first voltage signal and the second voltage signal meet the voltage constraint between the logic device and the storage array or not and generating a gating enable signal according to the voltage constraint; and the clock gating unit is used for closing or enabling the clock signal according to the gating enabling signal. Compared with a synchronous voltage regulation strategy, the system can effectively monitor the voltage constraint between the two paths of power supplies, and the reliability of synchronous voltage regulation is improved; compared with a step-by-step voltage regulation strategy, the voltage regulation time can be greatly shortened by simultaneously regulating two paths of voltage.

Description

technical field [0001] The present disclosure relates to the chip field, and in particular, relates to a voltage regulation method for a dual-rail memory, a memory system, and a system on chip. Background technique [0002] The trend towards miniaturization of integrated circuits has made processor manufacturers enthusiastic about how to reduce power consumption. There are two main methods for reducing power consumption in the system: Dynamic Voltage and Frequency Scaling (DVFS) and Adaptive Voltage and Frequency Scaling (AVFS). DVFS dynamically adjusts the clock frequency and power supply voltage of the system according to the different requirements of the computing power of the applications run by the processor, so as to achieve the purpose of energy saving. AVFS detects the system application environment in real time through sensors to determine the clock frequency and power supply voltage. [0003] However, the inventor found in research that most small integrated circ...

This brings up a new problem: how to regulate the two voltages

The existing technology adopts the scheme of parallel voltage regulation (i.e. synchronous regulation of two voltages), but the disadvantage of this scheme is parallel voltage regulation, and the voltage constraints between the two voltages may be destroyed during the process of simultaneous variation of the two voltages. It refers to the voltage constraint relationship that the logic device of the dual-rail memory and the power supply voltage of the storage array need to satisfy at all times
