IS42S16160G-7TLI

动态随机存取存储器 256M 16Mx16 143MHz SDR S动态随机存取存储器, 3.3V

32Meg x 8, 16Meg x16  256Mb SYNCHRONOUS DRAM

OVERVIEW IS42S16160G-7TLI

ISSI's 256Mb Synchronous DRAM achieves high-speed

data transfer using pipeline architecture. All inputs and

outputs signals refer to the rising edge of the clock input.

The 256Mb SDRAM is organized as follows.

The IS42S16160G-7TLI 256Mb SDRAM is a high speed CMOS, dynamic

random-access memory designed to operate in 3.3V Vdd

and 3.3V Vddq memory systems containing 268,435,456

bits. Internally configured as a quad-bank DRAM with a

synchronous interface. Each 67,108,864-bit bank is organized

as 8,192 rows by 512 columns by 16 bits or 8,192

rows by 1,024 columns by 8 bits.
