10. Test conditions assume signal transition time of 3 ns or less, timing reference levels of V
specified I

14. The internal write time of the memory is defined by the overlap of WE, CE = V
these signals can terminate a write by going inactive. The data input setup and hold timing must refer to the edge of signal that terminates write.
