62256 NVRAM Module

No More Batteries!

This is a premium quality nonvolatile RAM (NVRAM) replacement for the 62256 RAM used in pinball / arcade machines.

Replaces a 62256 or compatible pinout 32k x 8 SRAM. These modules use CYPRESS F-RAM nvram ICs rated at 151-year data retention & 100 trillion reads/writes. Module installs easily into any IC socket.

Batteries leak. Even brand new batteries from major brands have leaked a year or two later for no apparent reason and cause hundreds of dollars in repairs or replacement of boards and components affected. Upgrading to NVRAM will save you time, money and any future worry of battery damage. It's one of the best mods you can do to your games!


Some boards require desoldering the 62256 RAM currently on the board and installation of an IC socket (all Williams pinball games). If you do not have proper equipment or experience to perform the upgrade, please hire a professional to upgrade your board. Any attempt to modify your board is AT YOUR OWN RISK. See our article on an example of an NVRAM upgrade that requires soldering.

NVRAM is shipped in anti-static foam & anti-static bag. An IC socket is included.

See the COMPATIBILITY INFO below for game compatibility.



For pinball machines, refer to this Pinball NVRAM Game List to find what type of NVRAM you need for each game you'd like to upgrade. This will also help identify what games are plug-and-play and which require soldering for installation.

Additionally, check out the compatibility chart below for board diagrams showing the location of the RAM on the board, difficulty of the installation & any other usage/installation notes.

Plug-and-Play on all Whitestar games that used a 62256 RAM and/or have their "JP1" jumper (directly below the RAM chip on many of these boards) set to the 32k RAM setting.

You can get by with a 6264 NVRAM Module on many of these games, but the 62256 NVRAM Module is also an option if you want to replace like-with-like on your game.

NOT PLUG-AND-PLAY. Requires removal of existing RAM & installation of a socket! Williams WPC games did not have their RAM socketed from the factory. Unless someone has replaced the RAM and installed a socket, you will need to remove the existing RAM IC and install a 28-pin socket. Rated higher difficulty due to thin traces on Williams WPC MPUs. Additionally there may be a jumper change required.

Note: Games could use either a 62256 SRAM or 6264 SRAM. If your game is currently using a 62256 SRAM at U8 no changes are needed. If your game currently has a 6264 in it, you may want to consider just purchasing the 6264 NVRAM Module to avoid having to make any jumper changes.

Jumper Settings:
62256 = remove R93 and install jumper W3
*Only needed if your existing ram IS NOT a 62256<

Real-time clock will not function correctly on any games that utilized the clock for Midnight Madness Mode or other special time-sensitive modes. Midnight Madness Mode will not start at the correct time on Dirty Harry, Johnny Mnemonic, WHO Dunnit, Theatre of Magic, Congo, Junk Yard or NBA Fastbreak. In addition to this music on Creature From the Black Lagoon based on different dates will be affected. Twilight Zone's clock on the playfield will not show the correct time. There may be other games affected in addition to those listed here. Basically these functions will still work, but will not be based on the correct time since with nvram installed the real-time clock does not get updated when the machine is powered off.

Your current RAM might not be labeled as a "62256" -- some RAM manufacturers used different numbering on their RAM. The easiest thing to do is to write down the numbers on the RAM IC (located via the pictures above) and Google it to see if it's an 8K SRAM (6264) or 32K SRAM (62256). If in doubt, please contact us with a picture of your RAM or the number on the chip and we'll help you out.

This memory may also work in other applications where a 62256 RAM is used, but cannot be guaranteed to work in applications not listed & should not replace memory in critical circuits without proper testing. Note that the F-RAM chips latch each address on the falling edge of the /CE (chip enable) line, so in the hardware being upgraded the /CE line must be toggled for every read/write (not tied to GND). The chip enable circuit can be verified via schematic, but the toggling of the chip enable line on every read/write would need to be verified via logic analyzer. If you find this nvram compatibile with other devices, please let us know.

Note: The underlying nvram chip / IC used in these modules is ~$15 per chip. This is parts cost for the NVRAM chip itself BEFORE other material & business costs of assembling. If your game can use 6264 NVRAM by switching jumpers you can save a few bucks by going with the 6264 NVRAM instead.
