Product Description

The Hynix HY5RS573225 is a high-speed CMOS, dynamic random-access memory containing 268,435,456 bits. The Hynix HY5RS573225 is internally configured as a quad-bank DRAM. The Hynix HY5RS573225 uses a double data rate architecture to achieve high-speed operation The double data rate architecture is essentially a 4n-prefetch architecture, with an interface designed to transfer two data words per clock cycle at the I/O pins. A single read or write access for the Hynix HY5RS573225 consists of a 4n-bit wide, every two-clock-cycles data transfer at the internal DRAM core and two corresponding n-bit wide, one-half-clock-cycle data transfers at the I/O pins. Read and write accesses to the Hynix HY5RS573225 is burst oriented; accesses start at a selected locations 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 selectthe bank; A0-A11 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. Prior to normal operation, the Hynix HY5RS573225 must be Initialized.
