The KAIST research team said that the technology can be used as an energy efficient computing architecture for battery-powered flexible electronic systems, such as mobile and wearable devices.
The memristive nonvolatile logic-in-memory circuit is designed to simultaneously enable data storage and logic operation.
KAIST explained that its device can minimise energy consumption and time delay because it does not require data transfer between memory and processor.
Nonvolatile, polymer-based memristors and flexible back-to-back Schottky diode selector devices on plastic substrates were all explored. Unlike the conventional architecture, the team claimed the memristive nonvolatile logic-in-memory will consume a minimal amount of standby power. The team also said that this one-selector-one memristor (1S-1M) will solve the issue of sneak currents.
KAIST implemented single-instruction multiple-data, which it said, calculated multiple values at once.
The proposed parallel computing method using a memristive nonvolatile logic-in-memory circuit apparently provided a low-power circuit platform for battery-powered flexible electronic systems and the team said it has a variety of potential applications.
Professor Sung-Yool Choi, one of the device developers, said: “Flexible logic-in-memory circuits integrating memristor and selector device can provide flexibility, low power, memory with logic functions. This will be a core technology that will bring innovation to mobile and wearable electronic systems.”
