Challenges using Everspin MR4A16B

1. MRAM is vulnerable when exposed to external magnetic fieldData corruption in the write cycle and soft errors in the read cycle

Reference bits are flipped hard resulting in permanent non-functionality of the entire memory

2. High operating current and standby current with low access speedHigh end devices like PLC, servers and gaming machines require operation at high speeds and low currents

Everspin MR4A16B has a poor access speed of 35 ns

High operating current (Icc–110 mA @ 35 ns) and high standby current (Isb–9 mA)

3. Everspin is a fabless startup company that is financially weakLimited supply having shipped only ~5 million units till date with lead times of 8 to 10 weeks

Issues regarding long term support and future roadmaps

16 Mb parallel NVSRAM solves these problemsImmune to external magnetic field as NVSRAM is based on secure SONOS technology

Provides an access speed of 25 ns with an operating current of 90 mA and standby current of 0.5 mA

Assured Supply & Customer Support: Long-term supplier with over 20 years of supplying

Concrete past (shipped more than 150 million units) and clear future roadmap to build 32 Mb density parallel NVSRAM after 16 Mb is in production

16 Mb parallel NVSRAM is a fast and reliable product with a stable supply and long term support from Cypress

Gaming Machine

External magnetic field can corrupt the critical data which can create issues in the transaction process

“16Mb NVSRAM uses an additional capacitor for Vcap to perform Autostore operation which consumes extra board space”The capacitor is very small in size with the required capacitance of only 27 µF (typical) and max 120 µF

16Mb NVSRAM comes with an embedded RTC (watchdog timer, alarm, clock) which is not available in MRAM which actually saves more board space.

16Mb NVSRAM + capacitor costs less than 16Mb MRAM

“MR4A16B has ECC functionality in it”ECC identifies soft memory bit errors which are the errors primarily resulting from an MRAM bit not being correctly programmed.

The errors are identified and corrected during a read or a write cycle.

16Mb parallel NVSRAM doesn’t generate memory bit errors during a read or write cycle so there is no need for ECC in it.
