32M x 85.4 ns0°C ~ 70°C（TA）

Overview

The 256Mb SDRAM is a high-speed CMOS, dynamic random-access memory containing 268,435,456 bits. It is internally configured as a quad-bank DRAM with a synchronous interface (all signals are registered on the positive edge of the clock signal, CLK). Each of the x4’s 67,108,864-bit banks is organized as 8192 rows by 2048 columns by 4 bits. Each of the x8’s 67,108,864-bit banks is organized as 8192 rows by 1024 columns by 8 bits. Each of the x16’s 67,108,864-bit banks is organized as 8192 rows by 512 columns by 16 bits.

• PC100- and PC133-compliant• Fully synchronous; all signals registered on positive edge of system clock• Internal, pipelined operation; column address can be changed every clock cycle• Internal banks for hiding row access/precharge• Programmable burst lengths: 1, 2, 4, 8, or full page• Auto precharge, includes concurrent auto precharge and auto refresh modes• Self refresh mode (not available on AT devices)• Auto refresh – 64ms, 8192-cycle refresh (commercial and industrial) – 16ms, 8192-cycle refresh (automotive)• LVTTL-compatible inputs and outputs• Single 3.3V ±0.3V power supply
