3 / 17 page 128M GDDR SDRAM K4D263238E-GC - 3 - Rev 1.7 (Nov. 2003) The K4D263238E is 134,217,728 bits of hyper synchronous data rate Dynamic RAM organized as 4 x1,048,576 words by 32 bits, fabricated with SAMSUNG’s high performance CMOS technology. Synchronous features with Data Strobe allow extremely high performance up to 3.2GB/s/chip. I/O transactions are possible on both edges of the clock cycle. Range of operating frequencies, programmable burst length and programmable latencies allow the device to be useful for a variety of high performance memory system applications. • VDD/VDDQ = 2.8V ± 5% for -GC25 • VDD/VDDQ = 2.5V ± 5% for -GC2A/33/36/40/45 • SSTL_2 compatible inputs/outputs • 4 banks operation • MRS cycle with address key programs -. Read latency 3, 4, 5 (clock) -. Burst length (2, 4, 8 and Full page) -. Burst type (sequential & interleave) • Full page burst length for sequential burst type only • Start address of the full page burst should be even • All inputs except data & DM are sampled at the positive going edge of the system clock • Differential clock input GENERAL DESCRIPTION FEATURES • No Wrtie-Interrupted by Read Function • 4 DQS’s ( 1DQS / Byte ) • Data I/O transactions on both edges of Data strobe • DLL aligns DQ and DQS transitions with Clock transition • Edge aligned data & data strobe output • Center aligned data & data strobe input • DM for write masking only • Auto & Self refresh • 32ms refresh period (4K cycle) • 144-Ball FBGA • Maximum clock frequency up to 400MHz • Maximum data rate up to 800Mbps/pin FOR 1M x 32Bit x 4 Bank DDR SDRAM 1M x 32Bit x 4 Banks Graphic Double Data Rate Synchronous DRAM with Bi-directional Data Strobe and DLL ORDERING INFORMATION K4D263238E-VC is the Lead Free package part number.
