Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Dynamic Tuning of Control Signals
Associated with DRAM Memory Using the End-Point to End-Point Algorithm
Disclosed is a method that allows the control signals
associated with DRAM memory to be dynamically tuned for a variety of silicon
and board designs. Benefits include a reduction
In current technology, the tuning of various control signals
associated with DRAM is done using fixed tables within the firmware. This
requires that the firmware be updated periodically to change the tables, based
on silicon and board validation discovery. The existing methods occasionally
cause errors in the firmware, and require very close interaction between the
validation teams and the firmware teams.�
The disclosed method combines existing silicon features that
tune control signals, along with a software algorithm that performs memory
operations at various register settings (see Figure 1). The algorithm detects
whether the memory write/verify operation passes or fails in order to locate
the optimal setting. The algorithm initializes the memory controller tuning
registers to the end-point value, then progresses through the available values
until the memory write/verify operation passes. It then continues to progress
through the remaining settings until the operation begins to fail (see Figure
2). Next, the “pass” value is averaged with the “fail” value, and the average
is used as the dynamically determined value that is programmed into the
