NOTES:
(1)
Transition times are measured between VIH min (DC) and VIL max (DC).
Transition (rise and fall) of input signals have a fixed slope.
(2)
If the result of nominal calculation with regard to tCK contains more than one decimal place, the result is
rounded up to the nearest decimal place.
(i.e., tDQSS = 0.8 × tCK, tCK = 3.3 ns, 0.8 × 3.3 ns = 2.64 ns is rounded up to 2.7 ns.)
(3)
These parameters are measured from the differential clock (CLK and CLK ) AC cross point.
(4)
These parameters are measured from signal transition point of DS crossing VREF level.
(5)
The tREFI (max) applies to equally distributed refresh method.
The tREFI (min) applies to both burst refresh method and distributed refresh method.
In such case, the average interval of eight consecutive Auto-Refresh commands has to be more than 400 ns
always. In other words, the number of Auto-Refresh cycles which can be performed within 3.2 µs (8 × 400 ns)
is to 8 times in the maximum.
(6)
Low Impedance State is specified at VDDQ/2 ± 0.1 V from steady state.
(7)
High Impedance State is specified where output buffer is no longer driven.
(8)
These parameters depend on the clock jitter. These parameters are measured at stable clock.
(9)
Output timing is measured by using Normal driver strength at VDDQ = 1.7 V ∼ 1.9 V.
Output timing is measured by using Strong driver strength at VDDQ = 1.4 V ∼ 1.6 V.
(10)
These parameters are measured at tCK = minimum ∼6.0ns. When tCK is longer than 6.0ns, these parameters
are specified as below for all speed version.
tCKQS (MIN/MAX) = −0.6ns / 0.6ns, tAC (MIN/MAX) = −0.65ns / 0.65ns

Notes: 1. Regular Mode Register is chosen using the combination of BA0 = 0 and BA1 = 0.
2. “Reserved” places in Regular Mode Register should not be set.
3. A7 in Regular Mode Register must be set to “0” (low state).
Because Test Mode is specific mode for supplier.
4. Extended Mode Register is chosen using the combination of BA0 = 1 and BA1 = 0.
5. A0 in Extended Mode Register must be set to "0" to enable DLL for normal operation.

FUNCTIONAL DESCRIPTION
TM
Network FCRAM
The FCRAMTM is an acronym of Fast Cycle Random Access Memory.
The Network FCRAMTM is competent to perform fast random core access, low latency and high-speed data
transfer.
PIN FUNCTIONS
CLOCK INPUTS: CLK & CLK
The CLK and CLK inputs are used as the reference for synchronous operation. CLK is master clock input.
The CS , FN and all address input signals are sampled on the crossing of the positive edge of CLK and the
negative edge of CLK . The QS and DQ output data are aligned to the crossing point of CLK and CLK . The
timing reference point for the differential clock is when the CLK and CLK signals cross during a transition.
POWER DOWN: PD
The PD input controls the entry to the Power Down or Self-Refresh modes. The PD input does not have a
Clock Suspend function like a CKE input of a standard SDRAMs, therefore it is illegal to bring PD pin into
low state if any Read or Write operation is being performed.
CHIP SELECT & FUNCTION CONTROL: CS & FN
The CS and FN inputs are a control signal for forming the operation commands on FCRAMTM. Each
operation mode is decided by the combination of the two consecutive operation commands using the CS and
FN inputs.
BANK ADDRESSES: BA0 & BA1
The BA0 and BA1 inputs are latched at the time of assertion of the RDA or WRA command and are selected
the bank to be used for the operation. BA0 and BA1 also define which mode register is loaded during the Mode
Register Set command (MRS or EMRS).

ADDRESS INPUTS: A0~A14
Address inputs are used to access the arbitrary address of the memory cell array within each bank. The
Upper Addresses with Bank addresses are latched at the RDA or WRA command and the Lower Addresses are
latched at the LAL command. The A0 to A14 inputs are also used for setting the data in the Regular or
Extended Mode Register set cycle.

DATA INPUT/OUTPUT: DQ0~DQ17
The input data of DQ0 to DQ17 are taken in synchronizing with the both edges of DS input signal. The output
data of DQ0 to DQ17 are outputted synchronizing with the both edges of QS output signal.
DATA STROBE: DS, QS
Method of data strobe is chosen by Extended mode register.
(1) Unidirectional DS / QS mode
DS is input signal and QS is output signal. Both edges of DS are used to sample all DQs at Write operation.
Both edges of QS are used for trigger signal of all DQs at Read operation. During Write, Auto-Refresh and
NOP cycle, QS assert always “Low” level. QS is Hi-Z in Self-Refresh mode.
(2) Unidirectional DS / Free running QS mode
DS is input signal and QS is output signal. Both edge of DS are used to sample all DQs at Write operation.
Both edges of QS are used for trigger signal of all DQs at Read operation. QS assert always toggle signal
except Self-Refresh mode. This strobe type is easy to use for pin to pin connect application.
POWER SUPPLY: VDD, VDDQ, VSS, VSSQ
VDD and VSS are power supply pins for memory core and peripheral circuits.
VDDQ and VSSQ are power supply pins for the output buffer.
REFERENCE VOLTAGE: VREF
VREF is reference voltage for all input signals.

COMMAND FUNCTIONS and OPERATIONS
TC59LM818DMB are introduced the two consecutive command input method. Therefore, except for Power Down
mode, each operation mode decided by the combination of the first command and the second command from
stand-by states of the bank to be accessed.
Read Operation (1st command + 2nd command = RDA + LAL)
Issuing the RDA command with Bank Addresses and Upper Addresses to the idle bank puts the bank
designated by Bank Address in a read mode. When the LAL command with Lower Addresses is issued at the
next clock of the RDA command, the data is read out sequentially synchronizing with the both edges of QS
output signal (Burst Read Operation). The initial valid read data appears after CAS latency from the issuing
of the LAL command. The valid data is outputted for a burst length. The CAS latency, the burst length of read
data and the burst type must be set in the Mode Register beforehand. The read operated bank goes back
automatically to the idle state after lRC.
Write Operation (1st command + 2nd command = WRA + LAL)
Issuing the WRA command with Bank Addresses and Upper Addresses to the idle bank puts the bank
designated by Bank Address in a write mode. When the LAL command with Lower Addresses is issued at the
next clock of the WRA command, the input data is latched sequentially synchronizing with the both edges of DS
input signal (Burst Write Operation). The data and DS inputs have to be asserted in keeping with clock input
after CAS latency-1 from the issuing of the LAL command. The DS has to be provided for a burst length. The
CAS latency and the burst type must be set in the Mode Register beforehand. The write operated bank goes
back automatically to the idle state after lRC. Write Burst Length is controlled by VW0 and VW1 inputs with
LAL command. See VW truth table.
Auto-Refresh Operation (1st command + 2nd command = WRA + REF)
TC59LM818DMB are required to refresh like a standard SDRAM. The Auto-Refresh operation is begun with
the REF command following to the WRA command. The Auto-Refresh mode can be effective only when all banks
are in the idle state. In a point to notice, the write mode started with the WRA command is canceled by the REF
command having gone into the next clock of the WRA command instead of the LAL command. The minimum
period between the Auto-Refresh command and the next command is specified by lREFC. However, about a
synthetic average interval of Auto-Refresh command, it must be careful. In case of equally distributed refresh,
Auto-Refresh command has to be issued within once for every 3.9 µs by the maximum. In case of burst refresh
or random distributed refresh, the average interval of eight consecutive Auto-Refresh commands has to be more
than 400 ns always. In other words, the number of Auto-Refresh cycles that can be performed within 3.2 µs (8 ×
400 ns) is to 8 times in the maximum.
Self-Refresh Operation (1st command + 2nd command = WRA + REF with PD = “L”)
In case of Self-Refresh operation, refresh operation can be performed automatically by using an internal timer.
When all banks are in the idle state and all outputs are in Hi-Z states, the TC59LM818DMB become
Self-Refresh mode by issuing the Self-Refresh command. PD has to be brought to “Low” within tFPDL from the
REF command following to the WRA command for a Self-Refresh mode entry. In order to satisfy the refresh
period, the Self-Refresh entry command should be asserted within 3.9 µs after the latest Auto-Refresh command.
Once the device enters Self-Refresh mode, the DESL command must be continued for lREFC period. In addition,
it is desirable that clock input is kept in lCKD period. The device is in Self-Refresh mode as long as PD held
“Low”. During Self-Refresh mode, all input and output buffers are disabled except for PD , therefore the power
dissipation lowers. Regarding a Self-Refresh mode exit, PD has to be changed over from “Low” to “High” along
with the DESL command, and the DESL command has to be continuously issued in the number of clocks
specified by lREFC. The Self-Refresh exit function is asynchronous operation. It is required that one
Auto-Refresh command is issued to avoid the violation of the refresh period just after lREFC from Self-Refresh
exit.
Power Down Mode ( PD = “L”)
When all banks are in the idle state and DQ outputs are in Hi-Z states, the TC59LM818DMB become Power
Down Mode by asserting PD is “Low”. When the device enters the Power Down Mode, all input and output
buffers are disabled after specified time except for PD , CLK, CLK and QS. Therefore, the power dissipation
lowers. To exit the Power Down Mode, PD has to be brought to “High” and the DESL command has to be
issued for lPDA cycle after PD goes high. The Power Down exit function is asynchronous operation.

Mode Register Set (1st command + 2nd command = RDA + MRS)
When all banks are in the idle state, issuing the MRS command following to the RDA command can program
the Mode Register. In a point to notice, the read mode started with the RDA command is canceled by the MRS
command having gone into the next clock of the RDA command instead of the LAL command. The data to be set
in the Mode Register is transferred using A0 to A14, BA0 and BA1 address inputs. The TC59LM818DMB have
two mode registers. These are Regular and Extended Mode Register. The Regular or Extended Mode Register is
chosen by BA0 and BA1 in the MRS command. The Regular Mode Register designates the operation mode for a
read or write cycle. The Regular Mode Register has four function fields.
The four fields are as follows:
(R-1) Burst Length field to set the length of burst data
(R-2) Burst Type field to designate the lower address access sequence in a burst cycle
(R-3) CAS Latency field to set the access time in clock cycle
(R-4) Test Mode field to use for supplier only.
The Extended Mode Register has three function fields.
The three fields are as follows:
(E-1) DLL Switch field to choose either DLL enable or DLL disable
(E-2) Output Driver Impedance Control field.
(E-3) Data Strobe Select
Once those fields in the Mode Register are set up, the register contents are maintained until the Mode
Register is set up again by another MRS command or power supply is lost. The initial value of the Regular or
Extended Mode Register after power-up is undefined, therefore the Mode Register Set command must be issued
before proper operation.

(R-3) CAS Latency field (A6 to A4)
This field specifies the number of clock cycles from the assertion of the LAL command following the
RDA command to the first data read. The minimum value of CAS Latency depends on the frequency
of CLK. In a write mode, the place of clock that should input write data is CAS Latency cycles − 1.
