GENERAL DESCRIPTION
The Am29DS163D family consists of 16 megabit, 1.8
volt-only flash memory devices, organized as 1,048,576
words of 16 bits each or 2,097,152 bytes of 8 bits each.
Word mode data appears on DQ0–DQ15; byte mode
data appears on DQ0–DQ7. The device is designed to
be programmed in-system with the standard 1.8 volt
V
CC
supply, and can also be programmed in standard
EPROM programmers.
The device is available with an access time of 100 and
120 ns. The devices are offered in an 48-ball FBGA
package. Standard control pins—chip enable (CE#),
write enable (WE#), and output enable (OE#)—control
normal read and write operations, and avoid bus con-
tention issues.
The device requires only a
single 1.8 volt power sup-
ply
for both read and write functions. Internally
generated and regulated voltages are provided for the
program and erase operations.
removal of EEPROM devices. DMS also allows the
system software to be simplified, as it performs all
functions necessary to modify data in file structures,
as opposed to single-byte modifications. To write or
update a particular piece of data (a phone number or
configuration data, for example), the user only needs
to state which piece of data is to be updated, and
where the updated data is located in the system. This
i s a n a d va n ta g e c o m pa r e d t o s y s te m s w h e r e
user-written software must keep track of the old data
location, status, logical to physical translation of the
data onto the Flash memory device (or memory de-
vices), and more. Using DMS, user-written software
does not need to interface with the Flash memory di-
rectly. Instead, the user's software accesses the Flash
memory by calling one of only six functions. AMD pro-
vides this software to simplify system design and
software integration efforts.
The device offers complete compatibility with the
JEDEC single-power-supply Flash command set
standard.
Commands are written to the command
register using standard microprocessor write timings.
Reading data out of the device is similar to reading
from other Flash or EPROM devices.
The host system can detect whether a program or
erase operation is complete by using the device
sta-
tus bits:
RY/BY# pin, DQ7 (Data# Polling) and
DQ6/DQ2 (toggle bits). After a program or erase cycle
is completed, the device automatically returns to read-
ing array data.
The
sector erase architecture
allows memory sec-
tors to be erased and reprogrammed without affecting
the data contents of other sectors. The device is fully
erased when shipped from the factory.
Hardware data protection
measures include a low
V
CC
detector that automatically inhibits write opera-
tions during power transitions. The
hardware sector
protection
feature disables both program and erase
operations in any combination of the sectors of mem-
ory. This is achieved in-system or via programming
equipment.
The device offers two power-saving features. When
addresses are stable for a specified amount of time,
the device enters the
automatic sleep mode.
The
system can also place the device into the
standby
mode.
Power consumption is greatly reduced in both
modes.
Simultaneous Read/Write Operations with
Zero Latency
The Simultaneous Read/Write architecture provides
simultaneous operation
by dividing the memory
space into two banks. The device can improve overall
system performance by allowing a host system to pro-
gram or erase in one bank, then immediately and
simultaneously read from the other bank, with zero la-
tency. This releases the system from waiting for the
completion of program or erase operations.
Am29DS163D Features
The
Secured Silicon (SecSi) Sector
is an additional
64 Kbyte sector capable of being permanently locked
by AMD or customers. The
SecSi Sector Indicator
Bit
(DQ7) is permanently set to a 1 if the part is
fac-
tory locked,
and set to a 0 if
customer lockable.
This
way, customer lockable parts can never be used to re-
place a factory locked part.
Factory locked parts provide several options. The
SecSi Sector may store a secure, random 16 byte
ESN (Electronic Serial Number), customer code (pro-
grammed through AMD’s ExpressFlash service), or
both. Customer Lockable parts may utilize the SecSi
Sector as bonus space, reading and writing like any
other flash sector, or may permanently lock their own
code there.
DMS (Data Management Software)
allows systems
to easily take advantage of the advanced architecture
of the simultaneous read/write product line by allowing
