2.0 PRINCIPLES OF OPERATION
Flash memory augments EPROM functionality with
in-circuit electrical erasure and reprogramming.
The 28F020 introduces a command register to
manage this new functionality. The command
register allows for 100% TTL-level control inputs,
fixed
power
supplies
during
erasure
and
programming, and maximum EPROM compatibility.
In the absence of high voltage on the VPP pin, the
28F020 is a read-only memory. Manipulation of the
external memory control pins yields the standard
EPROM
read,
standby,
output
disable,
and
intelligent identifier operations.
The same EPROM read, standby, and output
disable operations are available when high voltage
is applied to the VPP pin. In addition, high voltage
on VPP enables erasure and programming of the
device. All
functions
associated with altering
memory
contents—intelligent
identifier,
erase,
erase verify, program, and program verify—are
accessed via the command register.
Commands are written to the register using
standard microprocessor write timings. Register
contents serve as input to an internal state
machine
which
controls
the
erase
and
programming circuitry. Write cycles also internally
latch addresses and data needed for programming
or
erase
operations.
With
the
appropriate
command
written
to
the
register,
standard
microprocessor read timings output array data,
access the intelligent identifier codes, or output
data for erase and program verification.
2.1
Integrated Stop Timer
Successive command write cycles define the
durations
of
program
and
erase
operations;
specifically, the program or erase time durations
are normally terminated by associated Program or
Erase Verify commands. An integrated stop timer
provides
simplified
timing
control
over
these
operations; thus eliminating the need for maximum
program/erase timing specifications. Programming
and erase pulse durations are minimums only.
When the stop timer terminates a program or erase
operation, the device enters an inactive state and
remains inactive until receiving the appropriate
Verify or Reset command.
