R.S.T. Pro2
Behavioral Testing Many memory manufacturers first test memory chips on a traditional ATE(Automatic Test Equipment) and then assemble them into modules. Although most ATE systems are great at catching Logical and Parametric Failures, they have no reliable way of replicating Behavioral Failures. This means that it is possible for a memory module to pass through the entire test process and still fail in the field. Therefore, ATE testers do not have the best possible fault coverage.
R.S.T. Pro2 identifies memory defects that may have passed every usual manufacturing test, but which can still fail in normal use. A major advantage of R.S.T. Pro2 compared to stand alone testers, is the capability of testing and validating RAM within the system environment, testing for Behavioral failures that are sensitive to system idiosyncrasy. Quickly isolate intermittent failures that do not necessarily prevent a system from booting, but surface during extended testing sessions.
Small but Robust Program Size R.S.T. Pro2’s powerful memory package is small in program size allowing the firmware to load itself into the least amount of memory possible. This allows for true low-level testing of RAM starting at memory address 2k exercising the complete range of a computer’s RAM.
Memory Test Algorithms There are many good approaches for testing memory. However, many tests simply throw various patterns at memory without much thought or knowledge of memory architecture. As Tier 1 partners with industry leading manufacturers, Ultra-X is able to continuously develop new sophisticated proprietary memory test algorithms to locate the most evasive memory failures. R.S.T. Pro2 has the broadest range of algorithms, for current and future memory chip technologies.
Self-Boot Technology R.S.T. Pro2 directly executes using Ultra-X’s exclusive Self-Boot Technology™ eliminating interference from memory drivers, TSRs, O/S limitation, and all other software layers. Utilizing direct hardware to hardware access commands, R.S.T. Pro2 is able to perform true precise low-level memory testing and validation.
