Definition of ‘Program’, ‘Bit-alterable Write’ and ‘Program on All 1s’:
Page programming
To program/write one data byte, two instructions are required: write enable (WREN), which
is one byte, and a page program (PP) sequence, which consists of four bytes plus data byte.
This is followed by the internal program cycle (of duration t
To spread this overhead, the page program (PP) instruction allows up to 64 bytes to be
programmed/written at a time, provided that they lie in consecutive addresses on the same
page of memory.
For optimized timings, it is recommended to use the page program (PP) instruction to
program all consecutive targeted bytes in a single sequence versus using several page
program (PP) sequences with each containing only a few bytes (see
and
Dual input fast program
The dual input fast program (DIFP) instruction makes it possible to program/write up to 64
bytes using two input pins at the same time.
For optimized timings, it is recommended to use the dual input fast program (DIFP)
instruction to program all consecutive targeted bytes in a single sequence rather than using
several dual input fast program (DIFP) sequences each containing only a few bytes (see
Section 6.11: Dual input fast program
Quad input fast program
The quad input fast program (QIFP) instruction makes it possible to program/write up to 64
bytes using four input pins at the same time.
For optimized timings, it is recommended to use the quad input fast program (QIFP)
instruction to program all consecutive targeted bytes in a single sequence rather than using
several quad input fast program (QIFP) sequences each containing only a few bytes (see
Section 6.12: Quad input fast program
– Program on Omneo™ P5Q PCM devices writes only 0s of the user data to the array
– Bit-alterable Write on Omneo™ P5Q PCM devices involves writing both 0s and 1s of
– Program on all 1s is similar to ‘program’ where only 0s are written to the array and 1s
and treats 1s as data masks. This is similar to programming on a floating gate flash
device.

written is previously set to all 1s. Program on all 1s is also referred to as PreSET Write.
