16Mx72 bits
Low Profile Registered DDR SDRAM DIMM
HYMD116G725A(L)8M-K/H/L
DESCRIPTION
Hynix HYMD116G725A(L)8M-K/H/L series is low profile registered 184-pin double data rate Synchronous DRAM Dual
In-Line Memory Modules (DIMMs) which are organized as 16Mx72 high-speed memory arrays. Hynix
HYMD116G725A(L)8M-K/H/L series consists of nine 16Mx8 DDR SDRAM in 400mil TSOP II packages on a 184pin
glass-epoxy substrate. Hynix HYMD116G725A(L)8M-K/H/L series provide a high performance 8-byte interface in 5.25"
width form factor of industry standard. It is suitable for easy interchange and addition.
Hynix HYMD116G725A(L)8M-K/H/L series is designed for high speed of up to 133MHz 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 ris-
ing 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 HYMD116G725A(L)8M-K/H/L 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 iden-
tify DIMM type, capacity and other the information of DIMM and the last 128 bytes are available to the customer.

Notes:
1. DQ-to-I/O wiring may be changed within a byte
2. DQ/DQS/DM/CKE/CS relationships must be
maintained as shown.
3. DQ/DQS resistors should be 22 Ohms.
4. VDDID strap connections(for memory device VDD, VDDQ);
Strap out :(open) : VDD=VDDQ
Strap In (Vss) : VDD=VDDQ
5. SDRAM placement alternates btw the back and
front sides for the DIMM
6. Address and control resistors should be 22 Ohms
