Even before the direction for a hidden refresh self-refresh, in a synchronous dynamic random access memory

摘要

a hidden selbstauffrischungsverfahren and a device for a synchronous dynamic direktzugriffspeicher have at least two zellenbu00e4nke, each of which includes a majority of zellenarrays.the hidden selbstauffrischungsvorrichtung includes a first eingabeleitung to enter an external first adressensignals to address each of the zellenbu00e4nke, a second eingabeleitung to enter an external second adressensignals to address each of the zellenarrays in the cell lenbu00e4nken,a counter to generate an address of each auffrischungsadressensignals for the majority of zellenarrays in one of the zellenbu00e4nke corresponding to a logical value of the first adressensignals from the first eingabeleitung, a adressenmultiplexer to select either of the refresher adressensignals of the meter or the second adressensignals of the second eingabeleitung,and at least two verriegelungsschaltkreise, according to the logical value of the first adressensignals from the first eingabeleitung individually driven, each of the at least two verriegelungsschaltkreise the adressensignal, selected by adressenmultiplexer worde n, a corresponding to the zellenbu00e4nke transmits.
