Current through Register Vol. 41, No. 3, September 23, 2024
A.
Critical memory shall be used to store all data that is considered vital to the
continued operation of the electronic gaming device. Critical memory storage
shall be maintained by a methodology that enables errors to be identified and
corrected in most circumstances. This methodology may involve signatures,
checksums, partial checksums, multiple copies, timestamps, or use of validity
codes. This includes:
1. All electronic meters
required in
11VAC20-20-440 E;
2. Current unused credits;
3. Electronic gaming device or game
configuration data;
4. Recall of
all wagers and other information necessary to fully reconstruct the game
outcome associated with the last 10 plays;
5. Software state, which is the last state
the electronic gaming device software was in before interruption; and
6. Error conditions that may have occurred on
the electronic gaming device that may include:
a. Memory error or control program
error;
b. Low memory battery, for
batteries external to the memory itself or low power source;
c. Program error or authentication mismatch;
and
d. Power reset.
B. Comprehensive checks
of critical memory shall be made continually to test for possible corruption.
In addition, all critical memory:
1. Shall
have the ability to retain data for a minimum of 180 days after power is
discontinued from the electronic gaming device. If the method used is an
off-chip battery source, it shall recharge itself to its full potential in a
maximum of 24 hours. The shelf life shall be at least five years. Memory that
uses an off-chip back-up power source to retain its contents when the main
power is switched off shall have a detection system that will provide a method
for software to interpret and act upon a low battery condition;
2. Shall only be cleared by a department
certified memory clear method; and
3. Shall result in an error if the control
program detects an unrecoverable memory error.
Statutory Authority: § 18.2-340.15 of the Code of
Virginia.
