7. Input/Output Function Description
Symbol
Type
Description
CK, CK
Input
Clock : CK and CK are differential clock inputs. All address and control input signals are sampled on the crossing of the positive edge of CK and negative edge of CK. Internal clock signals are derived from CK/CK.
CKE
Input
Clock Enable : CKE HIGH activates, and CKE LOW deactivates internal clock signals, and device input buffers and output drivers. Taking CKE LOW provides PRECHARGE POWER-DOWN and SELF REFRESH
operation (all banks idle), or ACTIVE POWER-DOWN (row ACTIVE in any banks). CKE is synchronous for all
functions except for disabling outputs, which is achieved asynchronously. Input buffers, excluding CK, CK and
CKE , are disabled during power-down and self refresh mode which are contrived for low standby power consumption.
CS
Input
Chip Select : CS enables(registered LOW) and disables(registered HIGH) the command decoder.
All commands are masked when CS is registered HIGH. CS provides for external bank selection on systems
with multiple banks. CS is considered part of the command code.
RAS, CAS, WE
Input
Command Inputs : RAS, CAS and WE (along with CS) define the command being entered.
LDM,UDM
Input
Input Data Mask : DM is an input mask signal for write data. Input data is masked when DM is sampled HIGH
along with that input data during a WRITE access. DM is sampled on both edges of DQS. DM pins include
dummy loading internally, to matches the DQ and DQS loading. For the x16, LDM corresponds to the data on
DQ0-DQ7 ; UDM correspons to the data on DQ8-DQ15.
BA0, BA1
Input
Bank Addres Inputs : BA0 and BA1 define to which bank an ACTIVE, READ, WRITE or PRECHARGE command is being applied.
A [n : 0]
Input
Address Inputs : Provide the row address for ACTIVE commands, and the column address and AUTO PRECHARGE bit for READ/WRITE commands, to select one location out of the memory array in the respective
bank. A10 sampled during a PRECHARGE command determines whether the PRECHARGE applies to one
bank (A10 LOW) or all banks (A10 HIGH). If only one bank is to be precharged, the bank is selected by BA0,
BA1. The address inputs also provide the op-code during a MODE REGISTER SET command. BA0 and BA1
determines which mode register( mode register or extended mode register ) is loaded during the MODE REGISTER SET command.
DQ
I/O
Data Input/Output : Data bus
LDQS,UDQS
I/O
Data Strobe : Output with read data, input with write data. Edge-aligned with read data, centered in write data.
it is used to fetch write data. For the x16, LDQS corresponds to the data on DQ0-DQ7 ; UDQS corresponds to
the data on DQ8-DQ15.

9. Mode Register Definition
9.1. Mode Register Set(MRS)
The mode register is designed to support the various operating modes of Mobile DDR SDRAM. It includes Cas latency, addressing mode,
burst length, test mode and vendor specific options to make Mobile DDR SDRAM useful for variety of applications. The default value of the
mode register is not defined, therefore the mode register must be written in the power up sequence of Mobile DDR SDRAM. The mode register is written by asserting low on CS, RAS, CAS and WE(The Mobile DDR SDRAM should be in active mode with CKE already high prior to
writing into the mode register). The states of address pins A0 ~ A12 and BA0, BA1 in the same cycle as CS, RAS, CAS and WE going low are
written in the mode register. Two clock cycles are required to complete the write operation in the mode register. Even if the power-up
sequence is finished and some read or write operation is executed afterward, the mode register contents can be changed with the same command and two clock cycles. This command must be issued only when all banks are in the idle state. If mode register is changed, extended
mode register automatically is reset and come into default state. So extended mode register must be set again. The mode register is divided
into various fields depending on functionality. The burst length uses A0 ~ A2, addressing mode uses A3, Cas latency(read latency from column address) uses A4 ~ A6, A7 ~ A12 is used for test mode. BA0 and BA1 must be set to low for proper MRS operation.

9.2. Extended Mode Register Set(EMRS)
The extended mode register is designed to support partial array self refresh or driver strength control. EMRS cycle is not mandatory and the
EMRS command needs to be issued only when either PASR or DS is used. The default state without EMRS command issued is half driver
strength, and Full array refreshed. The extended mode register is written by asserting low on CS, RAS, CAS, WE and high on BA1 ,low on
BA0(The Mobile DDR SDRAM should be in all bank precharge with CKE already high prior to writing into the extended mode register). The
state of address pins A0 ~ A12 in the same cycle as CS, RAS, CAS and WE going low is written in the extended mode register. Two clock
cycles are required to complete the write operation in the extended mode register. Even if the power-up sequence is finished and some read
or write operations is executed afterward, the mode register contents can be changed with the same command and two clock cycles. But this
command must be issued only when all banks are in the idle state. A0 - A2 are used for partial array self refresh and A5 - A6 are used for
driver strength control. "High" on BA1 and"Low" on BA0 are used for EMRS. All the other address pins except A0,A1,A2,A5,A6, BA1, BA0
must be set to low for proper EMRS operation. Refer to the table for specific codes.

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.

This derating table is used to increase tIS/tIH in the case where the input slew rate is below 1.0V/ns.
2) Minimum 3CLK of tDAL(= tWR + tRP) is required because it need minimum 2CLK for tWR and minimum 1CLK for tRP.
3) tAC(min) value is measured at the high Vdd(1.95V) and cold temperature(-25°C).
tAC(max) value is measured at the low Vdd(1.7V) and hot temperature(85°C).
tAC is measured in the device with half driver strength and under the AC output load condition (Fig.6 in next Page).
4) The specific requirement is that DQS be valid(High or Low) on or before this CK edge. The case shown(DQS going from
High_Z to logic Low) applies when no writes were previously in progress on the bus. If a previous write was in progress,
DQS could be High at this time, depending on tDQSS.

This derating table is used to increase tDS/tDH in the case where the DQ and DQS slew rates differ. The Delta Rise/Fall Rate is calculated as
1/SlewRate1-1/SlewRate2. For example, if slew rate 1 = 1.0V/ns and slew rate 2 =0.8V/ns, then the Delta Rise/Fall Rate =-0.25ns/V.

NOTE :
1) OP Code : Operand Code. A0 ~ A12 & BA0 ~ BA1 : Program keys. (@EMRS/MRS)
2) EMRS/ MRS can be issued only at all banks precharge state.
A new command can be issued 2 clock cycles after EMRS or MRS.
3) Auto refresh functions are same as the 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.
4) BA0 ~ BA1 : Bank select addresses.
5) If A10/AP is "High" at row precharge, BA0 and BA1 are ignored and all banks are selected.
6) During burst 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.
7) Burst stop command is valid at every burst length.
8) DM sampled at the rising and falling edges of the DQS and Data-in are masked at the both edges (Write DM latency is 0).
9) This combination is not defined for any function, which means "No Operation(NOP)" in Mobile DDR SDRAM.
