GENERAL DESCRIPTION
The K4M64163PK is 67,108,864 bits synchronous high data
rate Dynamic RAM organized as 4 x 1,048,576 words by 16 bits,
fabricated with SAMSUNG′s high performance CMOS technol-
ogy. Synchronous design allows precise cycle control with the
use of system clock, and I/O transactions are possible on every
clock cycle. Range of operating frequencies, programmable
burst lengths and programmable latencies allow the same
device to be useful for a variety of high bandwidth and high per-
formance memory system applications.

Mobile-SDRAM
Partial Array Self Refresh
1. In order to save power consumption, Mobile SDRAM has PASR option.
2. Mobile SDRAM supports 3 kinds of PASR in self refresh mode : Full Array, 1/2 of Full Array and 1/4 of Full Array.

Partial Self Refresh Area
Internal Temperature Compensated Self Refresh (TCSR)
Note :
1. In order to save power consumption, Mobile-SDRAM includes the internal temperature sensor and control units to control the
self refresh cycle automatically according to the two temperature range ; 45 °C and 85 °C(for Extended), 70 °C(for Commercial)
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.

B. POWER UP SEQUENCE
1. Apply power and attempt to maintain CKE at a high state and all other inputs may be undefined.
- Apply VDD before or at the same time as VDDQ.
2. Maintain stable power, stable clock and NOP input condition for a minimum of 200us.
3. Issue precharge commands for all banks of the devices.
4. Issue 2 or more auto-refresh commands.
5. Issue a mode register set command to initialize the mode register.
6. Issue a extended mode register set command to define DS or PASR operating type of the device after normal MRS.
For operating with DS or PASR , set DS or PASR mode in EMRS setting stage.
In order to adjust another mode in the state of DS or PASR mode, additional EMRS set is required but power up sequence is not
needed again at this time. In that case, all banks have to be in idle state prior to adjusting EMRS set.
