M27C160
PRESTO III Programming Algorithm
The PRESTO III Programming Algorithm allows
the whole array to be programed with a guaran-
teed margin in a typical time of 52.5 seconds. Pro-
gramming with PRESTO III consists of applying a
sequence of 50
μ
s program pulses to each word
until a correct verify occurs (see Figure 9). During
programing and verify operation a MARGIN
MODE circuit is automatically activated to guaran-
tee that each cell is programed with enough mar-
gin. No overprogram pulse is applied since the
verify in MARGIN MODE provides theneccessary
margin to each programmed cell.
Program Inhibit
Programming of multiple M27C160s in parallel
with different data is also easily accomplished. Ex-
cept for E, all likeinputs including G of the parallel
M27C160 may be common. A TTL low level pulse
applied to a M27C160’sE input and V
PP
at 12.5V,
will program that M27C160. A high level Einput in-
hibits the other M27C160s
grammed.
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
at V
IH
and G at V
IL
, V
PP
at 12.5V and V
