Abstract: A static random access memory device may include a write driver configured to float one of a first bitline and a second bitline connected to a memory cell and apply a write voltage to the other bitline in response to a logic state of a data signal; a write failure detector configured to receive a voltage of the floated bitline and output a write failure signal; and an assist voltage generator configured to generate a write assist voltage in response to the write failure signal. The write driver may additionally provide the write assist voltage to a bitline to which the write voltage is applied.

Abstract translation: 静态随机存取存储器装置可以包括写入驱动器，其被配置为浮置连接到存储器单元的第一位线和第二位线之一，并响应于数据信号的逻辑状态向另一个位线施加写入电压; 写入故障检测器，被配置为接收浮动位线的电压并输出写入失败信号; 以及辅助电压发生器，被配置为响应于写入失败信号产生写入辅助电压。 写入驱动器可以另外向写入电压施加到的位线提供写入辅助电压。
