Avalanche Technology: Two New Densities of 3rd-Gen Space-Grade Parallel Asynchronous x32-Interface High-Reliability P-SRAM Memory Devices

Avalanche Technology announced 2 new densities of its 3rd-gen space-grade parallel asynchronous x32-interface high-reliability P-SRAM (Persistent SRAM) memory devices, based on its Spin Transfer Torque Magneto-resistive RAM (STT-MRAM) technology.

These new densities of 2 and 8Gb give the system designer more choice, unifying the memory architecture and reducing power and size requirements to improve overall system reliability and life. With this development, the company is leading an evolution toward a new level of performance vs. cost for modern space electronic systems.

“We welcome the addition of Avalanche’s higher densities in the same physical footprint. The Avalanche 1Gbit MRAM with its single event effects (SEE) tolerance enables us to increase our board level boot memory from 4Mb (EEPROM) up to 128Mb (using MRAM), while saving board space for other uses,” said Robert Hillman, director engineering, Power Device Corporation (PDC). “With Avalanche we can maintain excellent upset rates while substantially increasing our boot memory density, saving on board space and providing a board level solution that’s configurable for a variety of mission requirements and price points.“

PDC chose the company‘s memory device for its Rad Hard Supercomputer for Space (SCS3740G2). Careful selection of boot memory was required, as the PDC product family has industry-leading board level upset rates of better than one uncorrected upset in 120 years. Its previous-gen used multiple 1Mb EEPROM’s, and Avalanche’s higher densities will extend to future upgrades without a redesign of the base platform. PDC can now support Low Earth Orbit requirement while also supporting Medium Earth Orbit and Geostationary Equatorial Orbit (GEO).

“With this new product release, Avalanche is innovating how a platform can be designed both for today and tomorrow, with an upgrade path for all future generations of a product family,” said Danny Sabour, VP, sales and marketing, Avalanche. “Avalanche enables systems deployments and upgrades with different Missions or Profiles in the field. With the new 8Gb P-SRAM device, customers can design unified memory architecture systems for high reliability aerospace applications, all in one small form factor.”

Options
The Parallel x32 Space Grade series is offered in 1, 2, 4 and 8Gb density options and has asynchronous SRAM compatible 45ns/45ns RW timings. Data is always non-volatile with >10^16 write cycles endurance and 10-year retention at 125°C. All 4 density options are available in a small footprint 142-Ball FBGA (17x11mm) package. These memory devices are offered in space grade (-40°C to 125°C) operating temperature range. Every unit goes through a 48-hour burn-in before it is shipped to customers.

All density options in the firm‘s Parallel x32 Space Grade series will be available to customers participating in the early access program. Customers can request early samples through the EAP page.
