SDRAM 16Mb H-die(x16)

512K x 16Bit x 2 Banks SDRAM

GENERAL DESCRIPTION

The K4S161622H is 16,777,216 bits synchronous high data rate Dynamic RAM organized as 2 x 524,288 words by 16 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 clock cycle. Range of operating frequencies, programmable burst length and programmable laten cies allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.
