GENERAL DESCRIPTION
The KM48S16030 is 134,217,728 bits synchronous high data rate Dynamic RAM organized as 4 x 4,194,304 words by 8 bits, fabricated with SAMSUNG′s high performance CMOS technology. Synchronous design allows precise cycle control with the use of system clock I/O transactions are possible on every clcok 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.
