Presto III programming algorithm
The Presto III Programming Algorithm allows the whole array to be programed with a
guaranteed margin in a typical time of 52.5 seconds. Programming with Presto III consists of
applying a sequence of 50µs program pulses to each word until a correct Verify occurs (see
Figure
During programing and verify operation a Margin Mode circuit is automatically activated to
guarantee that each cell is programed with enough margin. No overprogram pulse is applied
since the Verify in Margin Mode at V
margin to each programmed cell.
Figure 5.
Programming of multiple M27V160s in parallel with different data is also easily
accomplished. Except for E, all like inputs including G of the parallel M27V160 may be
common. A TTL low level pulse applied to a M27V160's E input and V
program that M27V160. A high level E input inhibits the other M27V160s from being
programmed.
A verify (read) should be performed on the programmed bits to determine that they were
correctly programmed. The verify is accomplished with E at V
and V
