suppliers of SW-222PIN and PDF data of SW-222PIN

Note : 1. The WRITE latency can be set from l t0 7 clocks. When the WRITE latency is set t0 1 0r 2 0r 3 clocks, the input buffers are turned on during the ACTIVE commands reducing the latency but added power. When the WRITE latency is set t0 4 ~7 clocks which must be greater than 7ns, the input bufters are turned on during the WRITE commands for lower power operation. 2. A low to high transition on the WDQS line is not allowed in the half clock prior to the write preamble. 3. The last rising edge of WDQS after the write postamble must be riven high by the controller. WDOS can not be pulled high by the on-die termination alone. 4. tHZ and tLZ transitions occur in the same access time windows as valid data transitions. These parameters are not referenced to a specific voltage level, but specify when the device output is no longer driving (HZ) or begins driving (LZ). 5. The cycle to cycle jitter over l~6 cycle short term jitter
