GENERAL DESCRIPTION
The Am29F010 in Known Good Die (KGD) form is a 1
Mbit, 5.0 Volt-only Flash memory. AMD defines KGD as
standard product in die form, tested for functionality
and speed. AMD KGD products have the same reli-
ability and quality as AMD products in packaged form.
Am29F010 Features
The Am29F010 device is organized as eight uniform
sectors of 16 Kbytes each for flexible erase capability.
This device is designed to be programmed in-system
with the standard system 5.0 Volt V
CC
supply. A power
supply providing 12.0 Volt V
PP
is not required for
program or erase operations.
The Am29F010 in KGD form offers access times of 90
ns and 120 ns, allowing high speed microprocessors to
operate without wait states. To eliminate bus conten-
tion the device has separate chip enable (CE#), write
enable (WE#) and output enable (OE) controls.
The device requires only a
single 5.0 volt power sup-
ply
for both read and write functions. Internally gener-
ated and regulated voltages are provided for the
program and erase operations.
The device is entirely command set compatible with the
JEDEC single-power-supply Flash standard
. Com-
mands are written to the command register using stan-
dard microprocessor write timings. Register contents
serve as input to an internal state machine that controls
the erase and programming circuitry. Write cycles also
internally latch addresses and data needed for the pro-
gramming and erase operations. Reading data out of
the device is similar to reading from other Flash or
EPROM devices.
Device programming occurs by executing the program
command sequence. This invokes the
Embedded
Program
algorithm—an internal algorithm that auto-
matically times the program pulse widths and verifies
proper cell margin.
Device erasure occurs by executing the erase com-
mand sequence. This invokes the
Embedded Erase
algorithm—an internal algorithm that automatically pre-
programs the array (if it is not already programmed) be-
fore executing the erase operation. During erase, the
device automatically times the erase pulse widths and
verifies proper cell margin.
The host system can detect whether a program or
erase operation is complete by reading the DQ7 (Data#
Polling) and DQ6 (toggle)
status bits
. After a program
or erase cycle has been completed, the device is ready
to read array data or accept another command.
The
sector erase architecture
allows memory sectors
to be erased and reprogrammed without affecting the
data contents of other sectors. The device is erased
when shipped from the factory.
The
hardware data protection
measures include a
low V
CC
detector automatically inhibits write operations
during power transitions. The
hardware sector pro-
tection
feature disables both program and erase oper-
ations in any combination of the sectors of memory,
and is implemented using standard EPROM program-
mers.
The system can place the device into the
standby mode
.
Power consumption is greatly reduced in this mode.
