The new NVRAM capability of the XH018 process
Erfurt, Germany: X-Fab Silicon Foundries says it is the first pure play foundry to offer an embedded nonvolatile random-access memory (NVRAM) process feature. Combining the benefits of quickly accessible SRAM with the nonvolatile data retention of EEPROM or flash memories, the new NVRAM capability of the XH018 process and supporting NVRAM compiler should enable customers to achieve the same or better functionality in significantly less chip area.
The compiler allows designers to create cost-effective, ready-to-use NVRAM blocks according to their specifications and try out various memory configurations before finalizing their design. The XH018 embedded NVRAM intellectual property (IP) is a design feature for fast, safe nonvolatile data storage in applications that require dynamic data storage, data availability when the supply voltage is powered down, and data protection in case of sudden power loss. Typical applications include industrial control and automotive applications, data transfer systems, RAID data storage, and security data handling.
Traditionally, nonvolatile RAM capability was created by combining SRAM with a separate EEPROM, requiring additional functionality for data handling and transfer, as well as added design effort to integrate and test the functionality. In contrast, X-Fab’s embedded NVRAM moves the SRAM content to the nonvolatile memory in a single cycle.
“Our customers find they can easily integrate this new embedded NVRAM functionality with the rest of their design into a single-chip solution,” said Jens Kosch, chief technology officer at X-Fab. “Our new NVRAM process feature enables more cost-effective designs, due to the smaller chip area required and the time savings achieved.”
The NVRAM process feature in the XH018 technology and the supporting NVRAM compiler are available now.
