AN6023 - NonVolatile SRAM (nvSRAM) Basics
A static random access memory (SRAM) loses its content when powered down, and is classified as a volatile memory. The memory is volatile because there is no data when power is restored to the device. Another example of a volatile memory is the dynamic random access memory (DRAM) used in all personal computers and laptops. A memory that retains (does not lose) its data without power, is classified as a nonvolatile memory. Examples of nonvolatile memories are nVSRAM and flash memories.
The audio visual tutorial below provides an introduction to the nvSRAM architecture & its functionality.
