EMRAM for RFID Tag

Key Benefits of using Embedded EMRAM
RFID tag with Integrated Circuit (IC) typically utilizes one or more of the following types of memory: ROM, EEPROM and RAM. Memory is either embedded on the IC or attached as discrete components.

As an embedded memory on IC, EMRAM is a high performance yet low cost alternative to these memory types and placement options. The cost savings is most significant when more than one memory types are used in the RFID tag.

Key Embedded EMRAM Features

• Very fast read and write: Read and write times are typically less than 50ns.

• Unlimited data storage endurance:  EMRAM is non-volatile, and retains data ad infinitum.

• Excellent Read & Write endurance:  EMRAM has unlimited write endurance.

• Simple memory management:  EMRAM has a random addressable data structure and uses a single voltage for Read & Write.

• Enables coding flexibility: Read-Only sectors are created post IC fabrication during programming. Application codes need not be designed into the machine code of the IC.

• Smallest silicon footprint: When embedded, EMRAM layers sit on top of the Logic IC. This could reduce chip surface area by up to 40%, significantly increasing the number of chips per wafer, and lowering unit cost as a result. With a 1T-8bit architecture, EMRAM takes up less space than SRAM and EEPROM.

• Low power.

• Radiation hardened: Inherently radiation hardened, EMRAM has zero soft error rate.

• Elevated temperature endurance: EMRAM storage layers are stable beyond 200˚C with compatible silicon substrates.
