Abstract

Purpose The purpose of this paper through the redundant monitoring unit reflecting the real-time temperature change of the array, an adaptive refresh circuit based on temperature is designed. Design/methodology/approach This paper proposed a circuit design for temperature-adaptive refresh with a fixed refresh frequency of traditional memory, high refresh power consumption at low temperature and low refresh frequency at high temperature. Findings Adding a metal oxide semiconductor (MOS) redundancy monitoring unit consistent with the storage unit to the storage bank can monitor the temperature change of the storage bank in real time, so that temperature-based memory adaptive refresh can be implemented. Originality/value According to the characteristics that the data holding time of dynamic random access memory storage unit decreases with the increase of temperature, a MOS redundant monitoring unit which is consistent with the storage unit is added to the storage array with the 2T storage unit as the core.

基于温度的2T阵列存储器自适应刷新电路设计

本文的目的是通过冗余监测单元反映阵列的实时温度变化，设计一种基于温度的自适应刷新电路。本文提出了一种温度自适应刷新电路设计，该电路采用传统存储器的固定刷新频率，低温时刷新功耗高，高温时刷新频率低。发现在存储库中加入与存储单元一致的MOS冗余监控单元，可以实时监控存储库的温度变化，实现基于温度的存储器自适应刷新。独创性/价值根据动态随机存取存储器存储单元数据保持时间随温度升高而减小的特点，在以2T存储单元为核心的存储阵列中增加了与存储单元相一致的MOS冗余监控单元。
