Fast Non-Volatile Memory Solutions Combining SRAM, DRAM and Sonos Flash

Analog/mixed-signal foundry supplier X-FAB Silicon Foundries and non-volatile memory specialist Anvo-Systems Dresden GmbH announced a cooperative agreement to offer high-speed non-volatile memory solutions that combine SRAM, DRAM and SONOS FLASH technologies.

The compact design results in a small silicon footprint that keeps device costs low. In this partnership, Anvo-Systems Dresden provides the IP and design expertise, and X-FAB provides the semiconductor manufacturing process, capacity and quality assurance.

The new nvSRAM solutions are for solutions requiring high reliability and security, such as for medical, communication, automotive, bio-technology and industrial control and metering applications.

Anvo-Systems Dresden’s novel nvSRAM approach offers multiple cost and energy-saving advantages compared to traditional flash and EEPROM solutions. It combines the typical SRAM features with robust, energy-efficient and cost-effective SONOS FLASH technology. The nvSRAM IP blocks come with unlimited and fast (20ns) read and write operation and a standard SRAM interface. A full parallel backup up to 125Mb/s guarantees fast store operation. Because the energy for storage is gathered during the normal operation cycle, no additional customer control circuitry is needed. In addition, the compact design and small silicon footprint hold down device costs.

To guarantee stable and reliable production of the nvSRAM solutions, X-FAB has installed a dedicated 0.18 micrometer manufacturing process on 8-inch wafers optimized for reliable memories based on SONOS architecture. The special memory solutions developed by Anvo-Systems Dresden survive γ-ray sterilization.

Anvo-Systems Dresden, after introducing its serial nvSRAM product families earlier this year, recently released a new parallel 256k nvSRAM product family with 25ns access time, unlimited R/W cycles, multiple STORE options and security features. The company will present its parallel nvSRAM solution at the electronica show in Munich.

As part of X-FAB’s X-CHAIN design and supply chain partner network, Anvo-Systems is among more than 30 companies specialized in chip design, test, assembly, supply chain management or turnkey IC solutions. The network partners provide additional services to X-FAB’s customers that go beyond the pure-play foundry approach.
