AUSTIN, Texas--(BUSINESS WIRE)--July 10, 2006--The first commercial Magnetoresistive Random Access Memory (MRAM) device is now in volume production and available from Freescale Semiconductor (NYSE:FSL) (NYSE:FSL.B).
Freescale's four megabit (Mbit) MRAM product is a fast, non-volatile memory with unlimited endurance - a combination of characteristics not available in any other individual semiconductor memory product. The device is built on a foundation of technology protected by more than 100 Freescale patents, including toggle-bit switching.
"With the commercialization of MRAM, Freescale is the first-to-market with a technology of tremendous possibilities and profound implications," said Bob Merritt, Semico Research. "Competition to become the first company to market MRAM technology was fierce. This is a significant achievement that certainly confirms the dedication of Freescale's engineering team."
MRAM uses magnetic materials combined with conventional silicon circuitry to deliver the speed of SRAM with the non-volatility of Flash in a single, high endurance device. Freescale's successful commercialization of this technology could hasten new classes of electronic products offering dramatic advances in size, cost, power consumption and system performance.
"The commercial launch of the industry's first MRAM product is a major milestone made possible by the pioneering research of Freescale technologists. It underscores our commitment to deliver breakthrough technology to our customers to address real-world challenges," said Sumit Sadana, senior vice president, Strategy and Business Development, and Chief Technology Officer, Freescale. "The unique capabilities of MRAM technology have numerous exciting applications in our target markets."
Freescale's first commercial MRAM product, called the MR2A16A, is appropriate for a variety of commercial applications such as networking, security, data storage, gaming and printers. The part is engineered to be a reliable, economical, single-component replacement for battery-backed SRAM units. The device also could be used in cache buffers, configuration storage memories and other applications that require the speed, endurance and non-volatility of MRAM.
About the MR2A16A
The MR2A16A is a commercial temperature range, 3.3 volt device featuring 35 nanosecond read and write cycle times. It is an asynchronous memory organized as 256K words by 16 bits. An industry standard SRAM pinout arrangement allows for system design flexibility without bus contention. The device is housed in a 400 mil TSOP type-II RoHS package. It is manufactured at Freescale's 200 millimeter Chandler Fab in Arizona.
Availability
The MR2A16A MRAM is available now from Freescale (www.freescale.com) and selected distributors.

Estas memorias magnéticas son más rápidas, y al no ser volátiles no necesitan de refresco como las memorias RAM convencionales lo que implica un menor consumo. Pero las SD/MMC/MS... tampoco necesitan de refresco ¿donde esta la novedad? Hablamos de memoria RAM, ninguna tarjeta de memoria actual soporta las velocidades que alcanzan las memorias RAM y mucho menos su intenso ciclo de vida.
Las características de este chip de memoria son:
- Voltaje 3.3 V.
- Rango de temperatura 0 - 70 ºC.
- Velocidad de acceso simétrica, lectura/escritura, de 35 ns.
- Acceso 8 o 16 bits
- Sistema de protección ante bajada de voltaje: desactiva la circuitería para prevenir la escritura ante una pérdida de voltaje.
- Memoria no volátil, los datos perduran durante al menos 10 años.
Sin embargo no nos confundamos, parece que Freescale Semiconductor lo que busca son compradores o inversores. ¿Por qué digo esto? Si leéis la de prensa veréis que se trata de un chip de 4 Mb (Megabits), es decir, 512 KB (KiloBytes).
