There are many ways to do this, including efficient memory utilization. One technology that can prove beneficial to wearable medical devices is ferroelectric RAM (FRAM).
A company that has heavily researched and ultimately applied FRAM is Cypress Semiconductor. William Wong (eeNews) talked with Doug Mitchell, Product Marketing Engineer MPS at Cypress, about the technology and how the company is taking advantage of it.
“Our team at Cypress is working on a next-gen update to our FRAM fail-safe storage solutions to build data-protection features into the memory itself, which we hope will encourage product developers and designers to incorporate secure features natively into their devices. Stay tuned for more on this in the near future.”
