Part Number: MYXxxSMS04GP32xxx-45/x
The Micross 4Gb Hermetic Space Grade Spin Torque MRAM, is manufactured utilizing Avalanche Technologies magneto-resistive random-access memory. This MRAM device architecture is analogous to Flash technology with an SRAM compatible READ/WRITE interface, a Configuration Register with enhanced ECC functionality and a Page Mode feature for improved performance. Data is non-volatile with a near infinite endurance and best in class, non-volatile memory data retention.
