Internal Temperature Compensated Self Refresh (TCSR)
Partial Array Self Refresh (PASR)
K4X51163PC - L(F)E/G
Note :
1. In order to save power consumption, Mobile-DDR SDRAM includes PASR option.
2. Mobile-DDR SDRAM supports three kinds of PASR in self refresh mode; Full array, 1/2 Array, 1/4 Array.
Note :
1. In order to save power consumption, Mobile DDR SDRAM includes the internal temperature sensor and control units to control the
2. If the EMRS for external TCSR is issued by the controller, this EMRS code for TCSR is ignored.
3. It has +/- 5 °C tolerance.
