nvSRAM

nvSRAM is one of the advanced NVRAM technologies that are fast replacing the battery-backed static random-access memory (BBSRAM), especially for applications that need battery-free solutions and long-term retention at SRAM speeds.

nvSRAMs are used in a wide range of situations: networking, aerospace, and medical, among many others[3] where the preservation of data is critical and where batteries are impractical.

[citation needed] When reading and writing data, a nvSRAM acts no differently than a standard asynchronous SRAM.

The nvSRAMs are in the CMOS process, with the EEPROM cells having a SONOS stack to provide nonvolatile storage.

When normal power is applied, the device looks and behaves in a similar manner as a standard SRAM.
