N.Y. Comp. Codes R. & Regs. tit. 9, § 5319.10 – Program memory, non-volatile memory and non-volatile devices used to store program memory.

(1) A gaming device shall have the ability to retain data for all critical memory, as set forth in section 5319.11 of this Part, and shall be capable of maintaining the accuracy of all information required for 30 days after power is discontinued from such gaming device.
(2) For rechargeable battery types only, if a battery backup is used as an off-chip battery source, such battery backup shall recharge itself to its full potential in a maximum of 24 hours. The shelf life of such battery backup shall be at least five years.
(3) NV memory that uses an off-chip backup power source to retain NV memory contents when the main power is switched off shall have a detection system that shall provide a method for software to interpret and act upon a low-battery condition before the battery reaches a level where such battery is no longer capable of maintaining NV memory.
(4) Clearing NV memory shall require access to the locked logic area or other secure method that the commission shall control.
(b) Function of NV memory reset.
Following the initiation of an NV memory reset procedure (using an approved NV memory-clear method), a game program shall execute a routine that initializes all bits in critical NV memory to the default state. All memory locations intended to be cleared through such NV memory-clear process shall be fully reset in all cases. The commission shall review and, in the discretion of the commission, approve the methodology for games that allow for partial NV memory clears.
(c) Default reel position or game display.
The default reel position or game display immediately after an NV memory reset shall not be the advertised top award on any selectable line. The default game display, upon entering game-play mode, also shall not be the advertised top award. This section applies to the base game only and not to any secondary bonus features.
(d) Configuration settings.
A configuration setting that causes an obstruction to the electronic accounting meters without an NV memory clear shall not be permitted. A change to the denomination shall be performed by a secure means, which includes access to the locked logic area or other secure method, so long as such method can be controlled by the commission (e.g., security tape, password or PIN-based controls).
