32Mx64 bits

Unbuffered DDR SDRAM DIMM

HYMD232646A(L)8-M/K/H/L

DESCRIPTION

Hynix HYMD232646A(L)8-M/K/H/L series is unbuffered 184-pin double data rate Synchronous DRAM Dual In-Line

Memory Modules(DIMMs) which are organized as 32Mx64 high-speed memory arrays. Hynix HYMD232646A(L)8-M/

K/H/L series consists of eight 32Mx8 DDR SDRAM in 400mil TSOP II packages on a 184pin glass-epoxy sub-

strate.Hynix HYMD232646A(L)8-M/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 HYMD232646A(L)8-M/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 HYMD232646A(L)8-M/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 identify

DIMM type, capacity and other the information of DIMM and the last 128 bytes are available to the customer.
