Panasonic has produced an English language video explaining resistive RAM technology and its application in microcontrollers.
Unfortunately I missed the European showing of Panasonic's microcontrollers with on-chip resistive RAM at this year's Embedded World exhibition.
The news that Panasonic was offering two types of 8-bit microcontroller – low power and general purpose – broke in May 2012 and the good news is that to accompany the appearance at Embedded World Panasonic made an English language Youtube video to explain the technology.
The move marks an alternative to the MCU plus non-volatile ferroelectric memory offering being made by some companies.
The resisitive RAM is based on tantalum oxide layers between tungsten plugs in a manner similar to a number of metal-oxide ReRAM schemes that are being researched by numerous companies. However, Panasonic has gone further by integrating the memory in a logic process and offering the resulting microcontrollers in evaluation kits.
The microcontrollers come with 128-kbytes of non-volatile instruction memory and 8-kbytes of non-volatile data memory. The low-power version operates at down to 0.9-V where it runs at 64-kHz clock frequency. The general-purpose version can be selected to run at between 1.8-V and 3.6-V at a clock frequency of 10-MHz.
The main claim for the embedded non-volatile memory is that it provides 10 year retention and good endurance of at least 100,000 program erase cycles at lower supply voltage and faster programming times than competitor memories, which results in lower power consumption.
