    • A memory capable of performing a refresh operation uncompetitively with an internal access operation also when an external access operation is non-cyclically performed is obtained. This memory comprises an external access detection portion detecting an external access operation, an access control portion performing an internal access operation on the basis of the external access operation and a refresh determination portion determining whether or not to perform a refresh operation on the basis of detection of the external access operation by the external access detection portion and the operating state of the access control portion. The access control portion performs the refresh operation before or after the internal access operation on the basis of the result of determination of the refresh determination portion.
    • 获得当外部访问操作非周期性地执行时,能够在内部访问操作中无效地执行刷新操作的存储器。 该存储器包括检测外部访问操作的外部访问检测部分,基于外部访问操作执行内部访问操作的访问控制部分以及基于检测来确定是否执行刷新操作的刷新确定部分 的外部访问检测部分的外部访问操作和访问控制部分的操作状态。 访问控制部分基于刷新确定部分的确定结果在内部访问操作之前或之后执行刷新操作。

    • A memory capable of performing a refresh operation without increasing current consumption is provided. This memory comprises a plurality of memory cells storing data, a delay circuit outputting a first address signal corresponding to the memory cells received from outside for a normal access operation with a delay of a prescribed period, a refresh control circuit outputting a second address signal corresponding to any of the memory cells subjected to a refresh operation of the data and a switching circuit switching and outputting the first address signal output from the delay circuit and the second address signal output from the refresh control circuit.
    • 提供了能够在不增加电流消耗的情况下执行刷新操作的存储器。 该存储器包括存储数据的多个存储单元,延迟电路,输出与从外部接收的存储单元相对应的第一地址信号,以进行规定周期的延迟的正常访问操作;刷新控制电路,输出相应的第二地址信号 对经过数据的刷新操作的任何存储器单元和切换电路进行切换并输出从延迟电路输出的第一地址信号和从刷新控制电路输出的第二地址信号。
