GENERAL DESCRIPTION
FOR 1M x 32Bit x 4 Bank DDR SDRAM
The K4D263238 is 134,217,728 bits of hyper synchronous data rate Dynamic RAM organized as 4 x 1,048,576 words by 32 bits, fabricated with SAMSUNG¢s high performance CMOS technology. Synchronous features with Data Strobe allow extremely high performance up to 1.8GB/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.

FEATURES
• 2.5V ± 5% power supply
• SSTL_2 compatible inputs/outputs
• 4 banks operation
• MRS cycle with address key programs
    -. Read latency 3,4 (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
• No Write Interrupted by Read function
• 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
