Mobile-DDR SDRAM

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.

- Full Array

- 1/2 Array

- 1/4 Array

Internal Temperature Compensated Self Refresh (TCSR)

Note :

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 three 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.

3. It has +/- 5

°C tolerance.
