Unbuffered DDR SO-DIMM
HYMD264M646B(L)F8-D43/D4
DESCRIPTION
Hynix HYMD264M646B(L)F8 series is unbuffered 200-pin double data rate Synchronous DRAM Small Outline Dual
In-Line Memory Modules (SO-DIMMs) which are organized as 64Mx64 high-speed memory arrays.
Hynix HYMD264M646B(L)F8 series consists of sixteen 32Mx8 DDR SDRAM in FBGA packages on a 200pin glassepoxy substrate. Hynix HYMD264M646B(L)F8 series provide a high performance 8-byte interface in 67.60mmX
31.75mm form factor of industry standard. It is suitable for easy interchange and addition.
Hynix HYMD264M646B(L)F8 series is designed for high speed of up to 200MHz and offers fully synchronous operations referenced to both rising and falling edges of differential clock inputs. While all addresses and control inputs are
latched on the rising edges of the clock, Data, Data strobes and Write data masks inputs are sampled on both rising
and falling edges of it. The data paths are internally pipelined and 2-bit prefetched to achieve very high bandwidth. All
input and output voltage levels are compatible with SSTL_2. High speed frequencies, programmable latencies and
burst lengths allow variety of device operation in high performance memory system.
Hynix HYMD264M646B(L)F8 series incorporates SPD(serial presence detect). Serial presence detect function is
implemented via a serial 2,048-bit EEPROM. The first 128 bytes of serial PD data are programmed by Hynix to identify
DIMM type, capacity and other the information of DIMM and the last 128 bytes are available to the customer.

Note :
1. VDDQ must not exceed the level of VDD.
2. VIL (min) is acceptable -1.5V AC pulse width with < 5ns of duration.
3. The value of VREF is approximately equal to 0.5VDDQ.
4. VID is the magnitude of the difference between the input level on CK and the input level on /CK.
5. The ratio of the pullup current to the pulldown current is specified for the same temperature and voltage, over the entire temper
ature and voltage range, for device drain to source voltages from 0.25V to 1.0V. For a given output, it represents the maximum difference between pullup and pulldown drivers due to process variation.

1.
This calculation accounts for tDQSQ(max), the pulse width distortion of on-chip circuit and jitter.
2.
Data sampled at the rising edges of the clock : A0~A12, BA0~BA1, CKE, /CS, /RAS, /CAS, /WE.
3.
For command/address input slew rate >=1.0V/ns
4.
For command/address input slew rate >=0.5V/ns and <1.0V/ns
This derating table is used to increase tIS/tIH in case where the input slew-rate is below 0.5V/ns.

6.
These parameters quarantee device timing, but they are not necessarily tested on each device, and they may be quaranteed by
design or tester correlation.
7.
Data latched at both rising and falling edges of Data Strobes(LDQS/UDQS) : DQ, LDM/UDM.
8.
Minimum of 200 cycles of stable input clocks after Self Refresh Exit command, where CKE is held high, is required to complete
Self Refresh Exit and lock the internal DLL circuit of DDR SDRAM.
9.
Min (tCL, tCH) refers to the smaller of the actual clock low time and the actual clock high time as provided to the device
(i.e. this value can be greater than the minimum specification limits for tCL and tCH).

tHP = minimum half clock period for any given cycle and is defined by clock high or clock low (tCH, tCL). tQHS consists of
tDQSQmax, the pulse width distortion of on-chip clock circuits, data pin to pin skew and output pattern effects and p-channel
to n-channel variation of the output drivers.

I/O Setup/Hold Delta Inverse Slew Rate Derating. This derating table is used to increase tDS/tDH in case where the DQ and
DQS slew rates differ. The Delta Inverse Slew Rate is calculated as (1/SlewRate1)-(1/SlewRate2). For example, if slew rate
1=0.5V/ns and Slew Rate2 = 0.4V/n then the Delta Inverse Slew Rate = -0.5ns/V.

14.
DQS, DM and DQ input slew rate is specified to prevent double clocking of data and preserve setup and hold times.
Signal transi tions through the DC region must be monotonic.
15.
tDAL = (tDPL / tCK ) + (tRP / tCK ). For each of the terms above, if not already an integer, round to the next highest integer.
tCK is equal to the actual system clock cycle time.
Example: For DDR266B at CL=2.5 and tCK = 7.5 ns,
tDAL = (15 ns / 7.5 ns) + (20 ns / 7.5 ns) = (2.00) + (2.67)
Round up each non-integer to the next highest integer: = (2) + (3), tDAL = 5 clock
16.
For the parts which do not has internal RAS lockout circuit, Active to Read with Auto precharge delay should be
tRAS - BL/2 x tCK.
17.
tHZ and tLZ transitions occur in the same access time windows as valid data trasitions. These parameters are not referenced
to a specific voltage level but specify when the device output is no longer driving (HZ), or begins driving (LZ).

( H=Logic High Level, L=Logic Low Level, X=Don’t Care, V=Valid Data Input, OP Code=Operand Code, NOP=No Operation )
Note :
1. LDM/UDM states are Don’t Care. Refer to below Write Mask Truth Table.
2. OP Code(Operand Code) consists of A0~A12 and BA0~BA1 used for Mode Registering duing Extended MRS or MRS.
Before entering Mode Register Set mode, all banks must be in a precharge state and MRS command can be issued after tRP
period from Prechagre command.
3. If a Read with Autoprecharge command is detected by memory component in CK(n), then there will be no command presented
to activated bank until CK(n+BL/2+tRP).
4. If a Write with Autoprecharge command is detected by memory compoment in CK(n), then there will be no command presented
to activated bank until CK(n+BL/2+1+tDPL+tRP). Last Data-In to Prechage delay(tDPL) which is also called Write Recovery Time
(tWR) is needed to guarantee that the last data has been completely written.
5. If A10/AP is High when Row Precharge command being issued, BA0/BA1 are ignored and all banks are selected to be
precharged.
