PRESTO II Programming Algorithm
PRESTO II Programming Algorithm allows pro-
gramming of the whole array with a guaranteed
margin, in a typical time of 13 seconds. Program-
ming with PRESTO II consists of applying a se-
quence of 100
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 provides nec-
essary margin to each programmed cell.
Program Inhibit
Programming of multiple M27C202s in parallel
with different data is also easily accomplished. Ex-
cept for E, all like inputs including G of the parallel
M27C202 may be common. A TTL low level pulse
applied to a M27C202’s P input, with E low and
VPP at 12.75V, will program that M27C202. A high
level E input inhibits the other M27C202s from be-
ing programmed.
Program Verify
A verify (read) should be performed on the pro-
grammed bits to determine that they were correct-
ly programmed. The verify is accomplished with E
and G at VIL, P at VIH,VPP at 12.75V and VCC at
6.25V.
