Autoselect Operation
A host system or external card reader/writer can deter-
mine the on-card manufacturer and device I.D. codes.
Codes are available after writing the 90h command to
the command register of a memory device, as shown in
Tables 5 through
10
. When the autoselect command is
issued to card address 00000h, the Miniature Card
returns the manufacturer I.D. If the autoselect
command is issued to card address 00001h, the Minia-
ture Card provides the device I.D.
To terminate the Auto Select operation, the
Read/Reset command sequence must be written to the
same device. The Autoselect command operates only
if the card is not write protected.
Sector Group Protection
Sector group protection can be used to permanently
disable program and erase operations in any combina-
tion of sector groups on the Flash memory components
used in AMD Miniature Cards. Each sector group con-
sists of four adjacent sectors within each device. The
pattern begins at SA0: SA0–3, SA4–7, SA8–11, and so
on. This protection must be performed prior to manu-
facturing the Miniature Cards. None of the sector
groups are protected on the standard Miniature Card
product offerings.
The host system must compensate for these protected
sector groups by determining their locations, then
ignoring those locations for reading and writing data. To
determine whether a sector group is protected, the
system would write the first three cycles of the Autose-
lect command, then on the fourth cycle, read at the
address (SA)02h, where SA is the sector address (see
Tables 11 and 12) within an individual device. A pro-
tected sector group produces “01h”, and an unpro-
tected sector group produces “00h”.
Write Operations
Write and erase operations are valid only when V
CC
is
above 4.5 V. This activates the state machine of an
addressed memory device. The command register is a
latch which saves address, commands, and data infor-
mation used by the state machine and memory array.
When Write Enable (WE#) and appropriate CE#
signals are at a logic-level low, and Output Enable
(OE#) is at a logic-high, the command register is
enabled for write operations. The falling edge of WE#
latches address information and the rising edge latches
data/command information.
Write or erase operations are performed by writing
appropriate data patterns to the command register of
accessed Flash memory devices.
The byte-wide commands are defined in Tables 6, 7,
9
,
and 10; word-wide commands are defined in Tables 5
and 8. Note that the Erase Suspend (B0h) and Erase
Resume (30h) commands are valid only while the
Sector Erase operation is in progress.
