clock mode, or K or Kn in single clock mode. The edge-aligned CQ and
CQn clocks accompany the read data for data capture in Stratix and
Stratix GX devices.
When writing to QDRII SRAM devices, data is generated by the write
clock, while the K clock is 90° shifted from the write clock, creating a
center-aligned arrangement.

ZBT SRAM
ZBT SRAM eliminate dead bus cycles when turning a bidirectional bus
around between reads and writes or between writes and reads. ZBT
allows for 100% bus utilization because ZBT SRAM can be read or written
on every clock cycle. Bus contention can occur when shifting from a write
cycle to a read cycle or vice versa with no idle cycles in between.
ZBT SRAM allows small amounts of bus contention. To avoid bus
contention, the output clock-to-low-impedance time (t
