5) Data retention procedure :
a) Write memory with CHECKERBOARD pattern
b) Power down to VCC = 2V for 250ms
c) Restore VCC to 4.5V, wait tr, read memory and compare with original pattern
d) Repeat the procedure with CHECKERBOARD pattern
6) Parameter tested go-no-go during functional test 4.
7) Parameter measured during functional test 4 using pattern March at 4.5V and 5.5V.
8) Guaranteed with output loading 5pF but not tested. Characterized at initial design and after major process
changes.
9) Guaranteed but not tested
10) The following pattern definitions apply :
a) ICCACT
Write loop pattern between Nmin and Nmax
