Mavriq CBRAM vs EEPROM: Side-by-Side Energy Consumption Demonstration

The power and energy consumption of today’s non-volatile memory devices may impede the growth of wearable electronics and other low power applications.

As an example, Adesto created a small heart monitor application board to measure the energy required to write information to the memory. The board is designed to have the memory devices run by a restricted amount of energy using finite capacitor reservoirs. The green trace is Mavriq 1.65V CBRAM, the two other traces are EEPROMS from competitive memory manufacturers.

As the memory device uses the energy stored in the capacitor for WRITE operations, eventually the capacitors’ charge is depleted and there is not enough canadian online pharmacy 24h energy to allow the memory device to function. When that happens, a small red LED is lighted, and the heart rate trace shows a flat line.

As you can see after less than 20 seconds, the first memory device consumes the power; after just a few seconds more the 2nd device also depletes the energy . The Mavriq CBRAM device continues to write using roughly 15-20 times less energy than the Floating Gate devices. Lower energy consumption means longer time between charging the devices and/or changing the batteries.

We’re Adesto. We’re inventing memory for Things.
