T431616

GRNERAL DESCRIPTION The T431616D/E SDRAM is a high-speed CMOS synchronous DRAM containing 16 Mbits. T431616D/E is internally configured as a dual 512K word x 16 DRAM with a synchronous interface (all signals are registered on the positive edge of the clock signal, CLK). Each of the 512K x 16 bit banks is organized as 2048 rows by 256 columns by 16 bits. Read and write accesses to the SDRAM are burst oriented; accesses start at a selected location and continue for a programmed number of locations in a programmed sequence. Accesses begin with the registration of a BankActivate command, T431616D/E is then followed by a Read or Write command.

The T431616D/E provides for programmable Read or Write burst lengths of 1, 2, 4, 8, or full page, with a burst termination option. An auto precharge function may be enabled to provide a self-timed row precharge that is initiated at the end of the burst sequence. The refresh functions, either Auto or Self Refresh are easy to use. By having a programmable mode register, the system can choose the most suitable modes to maximize its performance. T431616D/E is well suited for applications requiring high memory bandwidth and particularly well suited to high performance PC applications
