Rapid Programming Algorithm
A 50 µs CE pulse width is used to program. The address is
set to the first location. VCC is raised to 6.5V and VPP is
raised to 13.0V. Each address is first programmed with one
50 µs CE pulse without verification. Then a verifica-
tion/reprogramming loop is executed for each address. In
the event a word fails to pass verification, up to 10 succes-
sive 50 µs pulses are applied with a verification after each
pulse. If the word fails to verify after 10 pulses have been
applied, the part is considered failed. After the word verifies
properly, the next address is selected until all have been
checked. VPP is then lowered to 5.0V and VCC to 5.0V. All
words are read again and compared with the original data
to determine if the device passes or fails.
