- Single 3.3-V power supply commercial temperature range (0°C to 70°C)
- Symetrical high-speed read and write with fast access time (35 ns)
- Flexible data bus control
- 8 bit or 16 bit access
- Equal address and chip-enable access times
- Automatic data protection with low-voltage inhibit circuitry to prevent writes on power loss
- All inputs and outputs are transistor-transistor logic (TTL) compatible
- Fully static operation
- Full nonvolatile operation with 10 years minimum data retention
Magnetoresistive random access memory (MRAM) combines the speed and durability of SRAM and the non-volatility of Flash-onto a "single" chip. MRAM uses magnetic polarization, rather than electric charge, to store information, eliminating leakage and wear-out. It allows a single memory solution to replace multiple types of memory on a single chip-helping to enable faster, lower power, more cost-effective solutions for a variety of applications.
