Memory chip internal power administrative framework in deep shutdown mode

Original document(26 pages) 中文版

A depth turn �C off method of memory wafer includes switching off voltage regulator and charge pumping circuit, making suspension joint on memory unit voltage and using voltage obtained by external water voltage to replace internal power supply voltage of supporting circuit i.e. entering all memory units to precharge state before depth turn �C off mode is entered and making memory unit be suspension �C joint after depth turn �C off mode is entered to use depth turn �C off signal to control circuit of connecting voltage obtained by external wafer to supporting circuit.
