摘    要:提出了一种用于SRAM的低功耗位线结构,通过两种途径来实现低位线电压.在写操作时,利用单边驱动结构来抑制位线上充电电压的过大摆动;在读写操作时,改进预充结构来使位线电压保持较低.仿真表明,该结构使功耗大大节省.

关 键 词:静态存储器  位线  低功耗  SRAM  低功耗  线结构  仿真  改进  读写操作  充电电压  位线  驱动结构  单边  利用  线电压

Abstract:A low-power bitline architecture in SRAM was proposed, the low bitline voltage was realized by incorporating two techniques. A one-side driving scheme was used for the write operation to prevent the excessive full-swing charging on the bitlines. The precharging scheme was removed for both read and write operations, making the bitlines at low voltages. Simulation showed that such architecture could lead a significant power reduction.
Keywords:SRAM    bitline    low-power
