Everspin adds 4Mb density device to serial interface MRAM portfolio

CHANDLER, USA: Everspin Technologies announced the addition of a 4Mb product to its serial interface magnetoresistive random access memory (MRAM) family.

The MR25H40 provides a fast, simple Serial Peripheral Interface (SPI) solution that offers superior write speed, unlimited endurance, low standby and operating power, and more reliable data retention compared to available serial memory alternatives.

The MR25H40 is the latest addition to Everspin’s portfolio of high-performance non-volatile memory products designed to enhance systems using the SPI bus common on many microprocessors, microcontrollers and other integrated circuits. Everspin’s SPI MRAM family requires no write delay, runs at clock speeds as fast as 40 MHz, and provides automatic data protection on power loss and unlimited endurance with more than 20 years data retention.

Everspin has previously announced the upward-compatible 256Kb and 1Mb serial interface products, ideal for smart metering, industrial control, automotive and printer applications. Now, customers in these markets who need additional data storage can upgrade to the higher density 4Mb SPI MRAM or consider MRAM for applications that require more memory.

“Customers who may have been faced with limited options in the past can now use the 4Mb serial MRAM to directly replace EEPROM, Flash and FeRAM, and experience no write delays and unlimited read/write endurance,” said Phill LoPresti, president and CEO of Everspin Technologies. “The fast write time of the 4Mb serial MRAM also allows for new and exciting application architectures such as dynamically reconfigurable FPGAs.”

Serial MRAM implements a subset of commands common to today’s SPI EEPROM and Flash components, allowing MRAM to replace these components in the same socket and interoperate on a shared SPI bus. Serial MRAM offers superior write speed, unlimited endurance, low standby and operating power, and more reliable data retention compared to available serial memory alternatives.

Unlike other serial memories, both reads and writes can occur randomly in MRAM with no delay between writes. The MR25H40 is the ideal memory solution for applications that must store and retrieve data and programs quickly using a small number of I/O pins.
