GENERAL DESCRIPTION

The Micron 16Mb SDRAM is a high-speed CMOS, dynamic random-access memory containing 16,777,216 bits. It is internally configured as a dual memory array (the 4 Meg x 4 is a dual 2 Meg x 4, and the 2 Meg x 8 is a dual 1 Meg x 8) with a synchronous interface (all signals are registered on the positive edge of the clock signal, CLK). Each of the two internal banks is organized with 2,048 rows and either 1,024 columns by 4 bits (4 Meg x 4) or 512 columns by 8 bits (2 Meg x 8).

FEATURES

? Auto Precharge and Auto Refresh Modes

? Self Refresh Mode

? 64ms, 4,096-cycle refresh

? LVTTL-compatible inputs and outputs

? Single +3.3V ±0.3V power supply

? Longer lead TSOP for improved reliability (OCPL*)
