Programming of multiple M27W801s in parallel with different data is also easily
accomplished. Except for E, all like inputs including GV
common. A TTL low level pulse applied to a M27W801's E input, with V
program that M27W801. A high level E input inhibits the other M27W801s from being
programmed.
A verify (read) should be performed on the programmed bits to determine that they were
correctly programmed. The verify is accomplished with G at V

after the falling edge of E.
