Product Summary
The K4S641632H-TC75 is a 64Mb H-die SDRAM specification 54 TSOP-II. The K4S641632H-TC75 is a 67,108,864 bits synchronous high data rate dynamic RAM organized as 4 x 4,194,304 words by 4 bits, / 4 x 2,097,152 words by 8 bits, / 4 x 1,048,576 words by 16 bits, fabricated with high performance CMOS technology of SAMSUNG. Synchronous design allows precise cycle control with the use of system clock I/O transactions are possible on every clock cycle. Range of operating frequencies, programmable burst length and programmable latencies allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.
