摘要

采用40nm技术制备了1Mb SRAM,该SRAM具有有效利用非选择位线电荷的电荷收集器电路。这些电路减少了低压SRAM的两个主要功率浪费源:随机变化引起的多余位线摆动和非选择列的位线摆动。实现了以往工作中13.8pJ/Access/Mbit的最低功耗。

A 13.8pJ/Access/Mbit SRAM with charge collector circuits for effective use of non-selected bit line charges
1Mb SRAM with charge collector circuits for effective use of non-selected bit line charges has been fabricated in 40nm technology. These circuits reduce two major wasted power sources of the low voltage SRAM: excess bit line swing due to random variation and bit line swing of non-selected columns. The lowest power consumption of 13.8pJ/Access/Mbit in the previous works has been achieved.
