GENERAL DESCRIPTION
FOR 2M x 16Bit x 4 Bank DDR SDRAM
The K4D28163HD is 134,217,728 bits of hyper synchronous data rate Dynamic RAM organized as 4 x 2.097,152 words
by 16 bits, fabricated with SAMSUNG
鈥?/div>
high performance CMOS technology. Synchronous features with Data Strobe allow
s
extremely high performance up to 1.1GB/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.
