Wireless Memory Products （RFID）

Ramtron's MaxArias wireless memory combines the low power, high speed, and high endurance features of Ramtron's nonvolatile F-RAM memory technology with wireless access to enable innovative data collection capabilities for a broad range of applications.

Ramtron's first family of wireless memory devices, named the MaxArias WM710xx product line, enables read/write at the same range, superior speed and more. The MaxArias WM710xx will allow system integrators to extend their RF capabilities to create wireless data collectors capable of storing greater amounts of information locally on high-performance, RF-enabled ICs.

Symmetrical read & write

Write operations are zero power, resulting in no power or speed penalty for executing writes. Device reads and writes at the same distance.

Block-write integrity

SureWrite? feature prevents data corruption during full block-writes, ensuring complete data integrity

Superior write-speed

With speeds up to 6x faster than EEPROM, MaxArias wireless memory enables full memory block-write operations, allowing more data to be stored faster without "soak time."

Gamma tolerant

F-RAM is gamma radiation tolerant, which makes MaxArias wireless memory an ideal choice for applications that require sterilization.

The WM710xx is a family of RF-enabled wireless nonvolatile F-RAM memory employing an advanced ferroelectric process. The WM710xx’s interface is compliant with the EPC Class-1 Generation-2 UHF RFID Protocol for Communications at 860 MHz – 960 MHz, Version 1.2.0 Specification for RFID Air Interface.

A ferroelectric random access memory or F-RAM is nonvolatile and performs reads and writes like a RAM. It provides reliable data retention for 20 years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories. Unlike EEPROM’s, there is no power or speed premium paid for executing writes into the WM710xx as compared to read power and speed. Operation of the memory is fully symmetric: identical read and write characteristics in terms of power, speed, and reliability.
