Hynix HY5RS123235B 512Mbit (16MX32) GDDR3 BGA SDRAM
Availability: In stock
The Hynix HY5RS123235 is a high-speed CMOS, dynamic random-access memory containing 536,870,912 bits. The Hynix HY5RS123235 is internally configured as a eight-bank DRAM. The Hynix HY5RS123235 uses a double data rate architecture to achieve high-speed operation The double date 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 singleread or write access for the Hynix HY5RS123235 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 HynixHY5RS123235 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 of WRITE command. The address bits registered coincident with the ACTIVE command are used to select the bank and row to be accessed(BA0,BA1, BA2 select the 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 HY5RS123235 must be initialized.
