PRESTO II ProgrammingAlgorithm
PRESTO II Programming Algorithm allows the
whole array to beprogrammed with a guaranteed
margin,in atypical time of 52.5seconds.Program-
ming with PRESTO II consists of applying a se-
quenceof 100
μ
s programpulsesto eachbyte until
a correctverify occurs (see Figure 7). During pro-
gramming andverify operation,a MARGIN MODE
circuitis automaticallyactivatedinordertoguaran-
tee that each cell is programmed with enough
margin. No overprogrampulseis appliedsince the
verify in MARGIN MODE provides the necessary
marginto eachprogrammed cell.
ProgramInhibit
Programming of multiple M27C4001s in parallel
with different data is also easily accomplished.
Except for E, all like inputs including G of the
parallel M27C4001 may be common. A TTL low
level pulse applied to a M27C4001’sE input, with
V
PP
at 12.75V,willprogramthatM27C4001.Ahigh
level E input inhibits the other M27C4001s from
beingprogrammed.
Program Verify
A verify (read) should be performed on the pro-
grammedbits todeterminethat theywerecorrectly
programmed. The verify isaccomplishedwith Gat
