Description

The 512MByte (4.5Gb) SDRAM W364M72V-XSBX is a high-speed CMOS, dynamic random-access, memory using 9 chips containing 512M bits. Each chip is internally confi gured as a quadbank DRAM with a synchronous interface. Each of the chip's 134,217,728-bit banks is organized as 8,192 rows by 2,048 columns by 8 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 an ACTIVE command, which is then followed by a READ or WRITE command. The address bits registered coincident with the ACTIVE command are used to select the bank and row to be accessed (BA0, BA1 select the bank; A0-12 select the row). The address bits registered coincident with the READ or WRITE command are used to select the starting column location for the burst access.

The SDRAM W364M72V-XSBX provides for programmable READ or WRITE burst lengths of 1, 2, 4 or 8 locations, or the full page, with a burst terminate 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 4.5Gb SDRAM W364M72V-XSBX uses an internal pipelined architecture to achieve high-speed operation. This architecture is compatible with the 2n rule of prefetch architectures, but it also allows the column address to be changed on every clock cycle to achieve a high-speed, fully random access. Precharging one bank while accessing one of the other three banks will hide the precharge cycles and provide seamless, high-speed, random-access operation. The 4.5Gb SDRAM is designed to operate at 3.3V. An auto refresh mode is provided, along with a power-saving, power-down mode.
