... K4R271669F General Description Figure block diagram of the 128Mbit RDRAM device. It consists of two major blocks: a “core” block built from banks and sense amps similar to those found in other types of DRAM and a Direct Rambus TM interface block which permits an external controller to access this core ...

... K4R271669F Packet Format Figure 3 shows the formats of the ROWA and ROWR packets on the ROW pins. Table 3 describes the fields which comprise these packets. DR4T and DR4F bits are encoded to contain both the DR4 device address bit and a framing bit which allows the ROWA or ROWR packet to be recognized by the RDRAM device ...

... K4R271669F Field Encoding Summary Table 5 shows how the six device address bits are decoded for the ROWA and ROWR packets. The DR4T and DR4F encoding merges a fifth device bit with a framing bit. When neither bit is asserted, the device is not selected. Note that a ...

Page 11

... K4R271669F Table 7 shows the COP field encoding. The device must be in the ATTN power state in order to receive COLC packets. The COLC packet is used primarily to specify RD (read) and WR (write) commands. Retire operations (moving data from the write buffer to a sense amp) happen automatically. See Figure 18 for a more detailed description ...
