Everspin equips MRAM memory chip density of 1 Mbit Quad SPI interface

Company Everspin Technologies, has recently announced the first magnetoresistive memory chips ST-MRAM (Spin-Torque magnetoresistive RAM) for high-performance storage systems, has expanded its range again.

The density of new non-volatile memory chip, designated MR10Q010, is 1 Mbit. They are equipped with an interface Quad SPI, uniting four lines serial input-output. According to the manufacturer, the combination of Quad SPI MRAM memory type and allowed us to obtain very high-speed recording without delay characteristic of flash memory and EEPROM. Operating at a clock frequency of 104 MHz, the new memory is characterized by the capacity to read and write 52 MB / s. MR10Q010 supports the full set of commands Quad SPI, including the operations of fast reading and writing, in which the address and the data is transferred to all four lines to reduce the number of cycles synchronization.

Using the serial interface, eliminating the need for a smaller number of conclusions, reduce package size chip, simplifying PCB layout. MR10Q010 chips are available in standard packages SOIC 16-pin, whereas in the case of a parallel interface would need 20 pins.

Deliveries study samples Everspin promises to start the second quarter.
