Method and apparatus for reducing standby current in a dynamic random access memory during self refresh
摘要：
A dynamic random access memory including a first dynamic random access memory cell, a second dynamic random access memory cell to be refreshed, a sense amplifier, and a control circuit. The control circuit is configured to isolate the sense amplifier from at least one of the first dynamic random access memory cell and the second dynamic random access memory cell in an idle state and to couple the sense amplifier to only the second dynamic random access memory cell to be refreshed in a refresh state.
摘要（中）：

包括第一动态随机存取存储单元，要刷新的第二动态随机存取存储单元，读出放大器和控制电路的动态随机存取存储器。 控制电路被配置为将感测放大器与处于空闲状态的第一动态随机存取存储器单元和第二动态随机存取存储器单元中的至少一个隔离，并将读出放大器耦合到仅第二动态随机存取存储器单元 刷新状态。
