PRESTO II Programming Algorithm
PRESTO II Programming Algorithm allows pro-
gramming of the whole array with a guaranteed
margin, in a typical time of 6.5 seconds. Program-
ming with PRESTO II consists of applying a se-
quence of 100
μ
s program pulses to each word
until a correct verify occurs (see Figure 7). During
programming and verify operation, a MARGIN
MODE circuit is automatically activated in order to
guarantee that each cell is programmed with
enough margin. No overprogram pulse is applied
since the verify in MARGIN MODE at V
CC
much
higher than 3.6V, provides necessary margin to
each programmed cell.
Program Inhibit
Programming of multiple M27W102s in parallel
with different data is also easily accomplished. Ex-
cept for E, all likeinputs including G of the parallel
M27W102 may be common. ATTL low level pulse
applied to a M27W102’s P input, with E low and
V
PP
at12.75V, willprogram that M27W102. A high
level E input inhibits the other M27W102s from be-
ing programmed.
Program Verify
A verify (read) should be performed on the pro-
grammed bits to determine that theywere correct-
ly programmed. The verify is accomplished with E
and G at V
