Memory control system and control method thereof

Abstract

The invention provides a memory control system and a control method thereof. According to the control system, whether the new operation instruction is received within the preset time or not is judged, if the new operation instruction is not received, the system can enter the idle state, and the clock oscillator is at least closed in the idle state, so that the overall power consumption of the memory when the memory is not operated can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a memory control system and a control method thereof. Background technique [0002] In today's information age, the amount of information is increasing, people's demand for memory is increasing day by day, and the proportion of various memories in integrated circuit systems is also increasing. Therefore, reducing the power consumption of memory is the key to reducing the overall integrated circuit system. efficient means of power dissipation. [0003] Specifically, the power consumption of the memory mainly includes two parts; dynamic power consumption and static power consumption. Among them, the dynamic power consumption mainly refers to the power consumption generated when the memory performs read and write operations, and the static power consumption refers to the power loss generated when the memory does not perform any read or write operations. For static powe...

Problems solved by technology

For static power consumption, a variety of power control strategies have been proposed to reduce static power consumption; for dynamic power consumption, the circuits in the memory can be controlled to run at low frequencies to reduce dynamic power consumption, but this still avoids No power consumption, and it is difficult to eliminate the generation of leakage current
