137 / 149 page  November 2, 2004 pSRAM_Type07_13_A1 pSRAM Type 7 137 Adva nc e inf o r m at ion AC Characteristics Power Down Parameters Notes: 1. Applicable also to power-up. 2. Applicable when 4Mb and 8Mb Partial modes are programmed. Other Timing Parameters Notes: 1. Some data might be written into any address location if tCHWX(min) is not satisfied. 2. The Input Transition Time (tT) at AC testing is 5ns as shown in below. If actual tT is longer than 5ns, it can violate the AC specification of some of the timing parameters.
