GENERAL FOR 1M x 32Bit x 4 Bank GDDR2 SDRAM
The 4Mx32 GDDR2 is 134,217,728 bits of hyper synchronous data rate Dynamic RAM organized as 4 x 1,048,976 words by 32 bits, fabricated with SAMSUNG’s high performance CMOS technology. Synchronous features with Data Strobe allow extremely high performance up to 4GB/s/chip. I/O transactions are possible on both edges of the clock cycle. Range of operating frequencies, and programmable latencies allow the device to be useful for a variety of high performance memory system applications.
