5 / 71 page Internet Data Sheet Rev. 1.11, 2007-07 5 11172006-LBIU-F1TN HY[B/I]18T256[40/80/16]0B[C/F](L) 256-Mbit Double-Data-Rate-Two SDRAM 1.2 Description The 256-Mbit Double-Data-Rate-Two SDRAM is a high- speed CMOS Synchronous DRAM device containing 268,435,456 bits and internally configured as a quad-bank DRAM. The device is organized as either 16 Mbit × 4I/O × 4 banks, 8 Mbit × 8I/O × 4 banks or 4 Mbit ×16 I/O × 4 banks chip. These synchronous devices achieve high speed transfer rates starting at 400 Mb/sec/pin for general applications. See Table 1 for performance figures. The device is designed to comply with all DDR2 DRAM key features: • Posted CAS with additive latency, • Write latency = read latency - 1, • Normal and weak strength data-output driver, • Off-Chip Driver (OCD) impedance adjustment • On-Die Termination (ODT) function. All of the control and address inputs are synchronized with a pair of externally supplied differential clocks. Inputs are latched at the cross point of differential clocks (CK rising and CK falling). All I/Os are synchronized with a single ended DQS or differential DQS-DQS pair in a source synchronous fashion. A is used to convey row, column and bank address information in a RAS-CAS multiplexing style. The DDR2 device operates with a 1.8 V ± 0.1 V power supply. An Auto-Refresh and Self-Refresh mode is provided along with various power-saving power-down modes. The functionality described and the timing specifications included in this data sheet are for the DLL Enabled mode of operation. The DDR2 SDRAM is available in P(G)-TFBGA-60 and P(G)- TFBGA-84 packages. |
