Unbuffered DDR SO-DIMM
HYMD564M646B(L)P6-D43/D4/J
DESCRIPTION
Hynix HYMD564M646B(L)P6-D43/D4/J series is unbuffered 200-pin double data rate Synchronous DRAM Small Outline
Dual In-Line Memory Modules (SO-DIMMs) which are organized as 64M x 64 high-speed memory arrays. Hynix
HYMD564M646B(L)P6-D43/D4/J series consists of eight 32M x 16 DDR SDRAM in 400mil TSOP II packages on a
200pin glass-epoxy substrate. Hynix HYMD564M646B(L)P6-D43/D4/J series provide a high performance 8-byte inter-
face in 67.60mm x 31.75mm form factor of industry standard. It is suitable for easy interchange and addition.
Hynix HYMD564M646B(L)P6-D43/D4/J series is designed for high speed of up to 166/200MHz 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 HYMD564M646B(L)P6-D43/D4/J 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.
