IS42S32400B-6TL

Product Summary

The IS42S32400B-6TL is a high speed CMOS, dynamic random-access memory designed to operate in 3.3V VDD and 3.3V VDDQ memory systems containing 134,217,728 bits. Internally configured as a quad-bank DRAM with a synchronous interface. Each 33,554,432-bit bank is organized as 4,096 rows by 256 columns by 32 bits. The IS42S32400B-6TL includes an AUTO REFRESH MODE, and a power-saving, power-down mode. All signals are registered on the positive edge of the clock signal, CLK. All inputs and outputs are LVTTL compatible. The IS42S32400B-6TL has the ability to synchronously burst data at a high data rate with automatic column-address generation, the ability to interleave between internal banks to hide precharge time and the capability to randomly change column addresses on each clock cycle during burst access.
