Weebit ReRAM passes automotive qualification tests
The ReRAM non-volatile memory technology of Weebit Nano Ltd. has passed a series of high-temperature AEC-Q100 operational tests.
The company said the test results confirm the suitability of its ReRAM for high-temperature automotive applications.
The tests were conducted on a memory module comprising an array of 1T1R memory cells implemented in the S130 130nm manufacturing process of SkyWater Technology Inc.
The tests were:
- high-temperature cycling endurance – 100,000 cycles at 150 degrees C
- high-temperature data retention – 2,000 hours at 150 degrees C after 100,000 cycles at 150 degrees C
- high temperature operational life – a read after 1,000 hours at at 150 degrees C after 100,000 cycles at 150 degrees C
Weebit reported that in the three cases 3 lots of 77 units were tested with zero failures.
Such results would support the possibility of getting ReRAM accepted as an embedded memory for automotive microcontrollers.
It is notable that Weebit has recently announced automotive chip supplier OnSemi as licensee for its ReRAM technology
