EERAM is SRAM and EEPROM on one chip
You can almost hear them think in Microchip’s New Products kitchen: what if we put SRAM and EEPROM on one chip? What would you get? Interesting texture? Exciting flavour? What the heck, lets just do it. Sometimes experiments like this turn out bad, but not this time. The result is EERAM, the cheapest non-volatile SRAM technology currently on the market. No external power needed to keep the contents alive, combined with unlimited writing.
