Replacement 256K SRAM chip for SNES. This is OEM, which means it was actually pulled out of a genuine SNES game cartridge. It has been tested and works 100%. Use this SRAM chip to fix your game with a defective SRAM chip or use to make your own cart.

Remember, with the SNES that games that call for SRAM must have the right amount of SRAM! You cannot put an SRAM chip of the wrong size into the cart or the game will not work, even if the SRAM you put in is more than what the game needs. Make sure the game you are making or repairing called for a 256K SRAM chip in the first place.
