k. Repeat 4.11a through 4.11j for all other bits to be programmed.
l. If any bit does not verify as programmed, it shall be considered a programming reject.
a. Connect the device in the electrical configuration for programming. The waveforms on figure 5F and
b. Raise V
c. Address the PROM with binary address of the selected word to be programmed. Address inputs are
d. Disable the chip by applying V
e. Apply the V
f. Apply one V
Note: The PROM is supplied with fuses generating a high-level logic output. Programming a fuse will
cause the output to go to a low-level logic in the verify mode.
g. Other bits in the same word may be programmed sequentially by applying V
h. Repeat 4.13b through 4.13g for all other bits to be programmed.
i. Enable the chip by applying V
j. If any bit does not verify as programmed, it shall be considered a programming reject.
