PRESTO II Programming Algorithm
PRESTO II Programming Algorithm allows the
whole array to be programmed, with a guaranteed
margin, in a typical time of 13 seconds. Program-
ming with PRESTO II involves in applying a se-
quence of 100
μ
s program pulses to eachbyte until
a correct verify occurs (see Figure 7). During pro-
gramming and verify operation, aMARGIN MODE
circuit is automatically activated in order to guar-
antee that each cell is programmed with enough
margin. Nooverprogram pulse is applied since the
verify in MARGIN MODE at V
CC
muh higher than
3.6V provides necessary margin to each pro-
grammed cell.
Program Inhibit
Programming of multiple M27V101s in parallel
with different data is also easily accomplished. Ex-
cept for E, all likeinputs including G of the parallel
M27V101 may be common. A TTL low level pulse
applied to a M27V101’s P input, with E low and
V
PP
at 12.75V, will program that M27V101. A high
level E input inhibits the other M27V101s 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
IL
, P at V
IH
, V
PP
at 12.75V and V
CC
at
6.25V.
