Organization

Bandwidth (1/tBIT)

a

a.Data rate measured in Mbit/s per DQ differential pair. See “Timing Conditions” on page 58 and “ Timing Characteristics” on page 60.

Note that tBIT=tCYCLE/8

Latency(tRAC)

b

b.Read access time tRAC (= tRCD-R+tCAC) measured in ns. See “Timing Parameters” on page 61.

Binc

c.Timing parameter bin. See “Timing Parameters” on page 61. This is a measure of the number of interleaved read transactions needed

for maximum efficiency (the value Ceiling(tRC-R/tRR-D). For bin A, tRC-R/tRR-D=4, and for bin B, tRC-R/tRR-D=5 for bin C, tRC-R/tRR-D =6.
