Configuration Tables
The relationship between cycle time and read/write latency is selected by the user. The configuration table below lists valid
configurations available via Mode Register bits M0, M1, and M2 and the clock frequencies supported for each setting. Write
Latency is equal to the Read Latency plus one in each configuration to reduce bus conflicts
.

Notes:
1. tRC < 20 ns in any configuration is only available with –18 and –24 speed grades.
2. Minimum operating frequency for -18 is 370 MHz.
3. BL= 8 is not available.
4. The minimum tRC is typically 3 cycles, except in the case of a Write followed by a Read to the same bank. In this instance the minimum
tRC is 4 cycles.
