Address
The clock suspend mode occurs when a column access/burst is in progress and CKE is
registered LOW. In the clock suspend mode, the internal clock is deactivated, freezing
the synchronous logic.
For each positive clock edge on which CKE is sampled LOW, the next internal positive
clock edge is suspended. Any command or data present on the input balls when an in-
ternal clock edge is suspended will be ignored; any data present on the DQ balls
remains driven; and burst counters are not incremented, as long as the clock is suspended.
Exit clock suspend mode by registering CKE HIGH; the internal clock and related opera-
tion will resume on the subsequent positive clock edge.
