IS42S32800B-7B-TR

概觀

The ISSI IS42S32800B is a high-speed CMOS configured as a quad 2M x 32 DRAM with a synchronous interface (all signals are registered on the positive edge of the clock signal,CLK). Each of the 2M x 32 bit banks is organized as 4096 rows by 512 columns by 32 bits.Read and write accesses start at a selected locations in a programmed sequence. Accesses begin with the registration of a BankActive command which is then followed by a Read or Write command The ISSI IS42S32800B provides for programmable Read or Write burst lengths of 1,2,4,8,or full page, with a burst termination operation. An auto precharge function may be enable 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. These devices are well suited for applications requiring high memory bandwidth.
