AT27C400  
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 BYTE/VPP  
is raised to 13.0V. Each address is first programmed with  
one 50 µs CE pulse without verification. Then a verification/  
reprogramming loop is executed for each address. In the  
event a word fails to pass verification, up to 10 successive  
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.
