32Mx72 bits
Unbuffered DDR SO-DIMM
HYMD232M726A(L)8-J/M/K/H/L
DESCRIPTION
Hynix HYMD232M726A(L)8-J/M/K/H/L series is unbuffered 200-pin double data rate Synchronous DRAM Small Out-
line Dual In-Line Memory Modules (SO-DIMMs) which are organized as 32Mx72 high-speed memory arrays. Hynix
HYMD232M726A(L)8-J/M/K/H/L series consists of nine 32Mx8 DDR SDRAM in 400mil TSOP II packages on a 200pin
glass-epoxy substrate.
Hynix HYMD232M726A(L)8-J/M/K/H/L series is designed for high speed of up to 166MHz and offers fully synchro-
nous 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 HYMD232M726A(L)8-J/M/K/H/L series incorporates SPD(serial presence detect). Serial presence detect func-
tion 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.
