[Adr990] wants to make sure his Game Boy game saves aren’t lost to aging batteries. They’re stored in SRAM with a small coin cell inside the cartridge to keep the memory energized when the game is not being played. But if you pull out the battery in order to replace it the data will be [...]

Find you’re running out of memory and paying for more expensive chips just to plug this feature gap? Many of the upper offering of chips have the option of adding SRAM thanks to an on-chip hardware feature, but if you don’t have that this 512k SRAM add-on board can be used with any chip that [...]

How much memory do you really need? We suppose it’s not really our place to judge how you misuse use memory in your projects. But we do appreciate the clean and orderly technique that [Eric Rogers] uses to add multiple SPI SRAM chips to an Arduino. The heavy lifting is done with a CPLD shield [...]

[Andy] stuffed some more RAM onto an Arduino Mega and his three-part walk through on the design, construction, and software is a great read and one of the more ‘hard core’ Arduino builds we’ve seen. The build is centered around a 512K × 8 SRAM module [PDF warning]. Because the RAM is divided up into about 512,000 [...]

[Erik] wrote in letting us know that he just completed development of the Bobuino, a Arduino based on an ATmega1284. That chip is nice and beefy, most notably for having 16 KB of SRAM but it also boasts 4 KB of EEPROM, and 128 KB of program memory. But the upgraded chip isn’t the only [...]
