preceded charging device in a semiconductor memory device and preceded drawer method using the same

摘要

The invention relates to a preceded charging device in a semiconductor memory device and a preceded charging process, that is the same is used, published. The preceded charging device contains a memory array, in which a plurality of memory address areas is divided into at least two storage groups, and a preceded drawer - total command dec or for producing at least two preceded drawer signals corresponding to a preceded drawer - command signal and an address signal, wherein said at least two preceded drawer signals are output in each case with a time delay, which corresponds to a control signal, in order to the at least two storage groups, with a time delay precharge. For this reason, the peak current, in order to reduce the jumping of the power supply.
