GENERAL DESCRIPTION

The K4S51163PF is 536,870,912 bits synchronous high data
rate Dynamic RAM organized as 4 x 8,388,608 words by 16 bits,
fabricated with SAMSUNG’s high performance CMOS technol­ogy. 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 per­formance memory system applications.

NOTES:

1. The minimum number of clock cycles is determined by dividing the minimum time required with clock cycle time and then rounding off to the next
higher integer.

2. Minimum delay is required to complete write.

3. All parts allow every cycle column address change.

4. In case of row precharge interrupt, auto precharge and read burst stop.

NOTES :

1. Parameters depend on programmed CAS latency.

2. If clock rising time is longer than 1ns, (tr/2-0.5)ns should be added to the parameter.

3. Assumed input rise and fall time (tr & tf) = 1ns.
If tr & tf is longer than 1ns, transient time compensation should be considered,
i.e., [(tr + tf)/2-1]ns should be added to the parameter.

NOTES :

1. OP Code : Operand Code
A0 ~ A12 & BA0 ~ BA1 : Program keys. (@MRS)

2. MRS can be issued only at all banks precharge state.
A new command can be issued after 2 CLK cycles of MRS.

3. Auto refresh functions are the same as CBR refresh of DRAM.
The automatical precharge without row precharge command is meant by "Auto".
Auto/self refresh can be issued only at all banks precharge state.

Partial self refresh can be issued only after setting partial self refresh mode of EMRS.

4. BA0 ~ BA1 : Bank select addresses.

5. During burst read or write with auto precharge, new read/write command can not be issued.
Another bank read/write command can be issued after the end of burst.
New row active of the associated bank can be issued at tRP after the end of burst.

6. Burst stop command is valid at every burst length.

7. DQM sampled at the positive going edge of CLK masks the data-in at that same CLK in write operation (Write DQM latency
is 0), but in read operation, it makes the data-out Hi-Z state after 2 CLK cycles. (Read DQM latency is 2).

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 ; Max. 40 °C, Max. 70 °C.

2. If the EMRS for external TCSR is issued by the controller, this EMRS code for TCSR is ignored.

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.

EMRS cycle is not mandatory and the EMRS command needs to be issued only when DS or PASR is used.
The default state without EMRS command issued is the half driver strength and full array refreshed.
The device is now ready for the operation selected by EMRS.
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.
