SDRPlus vs. SDR
SDRPlus performs significantly better than SDR for complex data transfers, making it the ideal SECS driver for Big Data and data-intensive solutions that will enable more quality assurance analysis.

- Do you need to move larger volumes or more complex data (e.g., analysis data, large recipes files, or wafer maps) using SECS?
- Does your connectivity solution need additional memory that a native 64-bit architecture enables, or does it need to be compatible with other 64-bit applications?
Maintain your solution easily
SDRPlus complies with latest releases of SEMI E4 (SECS-I), SEMI E5 (SECS-II) and SEMI E37 (HSMS). Additional logging and analytics tools in SDRPlus make it easy to maintain and troubleshoot your connectivity solution.
Migrate from SDR to SDRPlus easily
Current SDR users who need a high-performance SECS driver can migrate easily to SDRPlus with minimal effort. We provide a backwards-compatible C/C++ SDR API and the SDRPlus Migration Guide will walk you through the process.
