9.3. Internal Temperature Compensated Self Refresh (TCSR)
1. In order to save power consumption, Mobile DDR SDRAM includes the internal temperature sensor and control units to control the self
refresh cycle automatically according to the two temperature ranges ; 45 °C and 85 °C.
2. If the EMRS for external TCSR is issued by the controller, this EMRS code for TCSR is ignored.
NOTE :
1) It has +/- 5 °C tolerance.
9.4. Partial Array Self Refresh (PASR)
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.
