All rights reserved. The ordering of accesses within a burst is determined by the burst length, the burst type, and the starting column address, as shown in Table CAS Latency CL CL is the delay, in clock cycles, between the registration of a READ command and the availability of the first piece of output data. The latency can be set to two or three clocks. If a READ command is registered at clock edge n, and the latency is m clocks, the data will be available by clock edge n + m. The DQ will start driving as a result of the clock edge one cycle earlier n + m - 1 , and provided that the relevant access times are met, the data will be valid by clock edge n + m. For example, assuming that the clock cycle time is such that all relevant access times are met, if a READ command is registered at T0 and the latency is programmed to two clocks, the DQ will start driving after T1 and the data will be valid by T2, as shown in Figure 4 on page Table 8 on page 10 indicates the operating frequencies at which each CL setting can be used.

The ordering of accesses within a burst is determined by the burst length, the burst type, and the starting column address, as shown in Table

CAS Latency CL

CL is the delay, in clock cycles, between the registration of a READ command and the availability of the first piece of output data. The latency can be set to two or three clocks.

If a READ command is registered at clock edge n, and the latency is m clocks, the data will be available by clock edge n + m. The DQ will start driving as a result of the clock edge one cycle earlier n + m - 1 , and provided that the relevant access times are met, the data will be valid by clock edge n + m. For example, assuming that the clock cycle time is such that all relevant access times are met, if a READ command is registered at T0 and the latency is programmed to two clocks, the DQ will start driving after T1 and the data will be valid by T2, as shown in Figure 4 on page Table 8 on page 10 indicates the operating frequencies at which each CL setting can be used.

Reserved states should not be used as unknown operation or incompatibility with future versions may result.

Micron Technology, Inc., reserves the right to change products or specifications without notice. 2006 Micron Technology, Inc. All rights reserved.

Operating Mode

The normal operating mode is selected by setting M7 and M8 to zero the other combinations of values for M7 and M8 are reserved for future use and/or test modes. The programmed burst length applies to both READ and WRITE bursts.

Test modes and reserved states should not be used because unknown operation or incompatibility with future versions may result.

Write Burst Mode

When M9 = 0, the burst length programmed via M0M2 applies to both READ and WRITE bursts when M9 = 1, the programmed burst length applies to READ bursts, but write accesses are single-location nonburst accesses.
