Unbuffered DDR SDRAM DIMM

HYMD232646A8J

DESCRIPTION

PRELIMINARY

Hynix HYMD232646A8J series is unbuffered 184-pin double data rate Synchronous DRAM Dual In-Line Memory Mod-

ules(DIMMs) which are organized as 32Mx64 high-speed memory arrays. Hynix HYMD232646A8J series consists of

eight 32Mx8 DDR SDRAM in 400mil TSOP II packages on a 184pin glass-epoxy substrate.Hynix HYMD232646A8J

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 HYMD232646A8J 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 HYMD232646A8J series incorporates SPD(serial presence detect). Serial presence detect function is imple-

mented 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.
