US09324072B1 Bit-flipping memory controller to prevent SRAM data remanence
A memory is organized into blocks. In a bit-flipping operation, a memory block is read, the read bit data values are inverted, and the inverted data is written back to the memory block. Inverted memory blocks are tracked by setting a flag bit in the memory block, or by storing a pointer to a memory block. In a read operation, a memory block is read and, if the tracking method indicates the memory block is inverted, the read data values are reverted before being returned. In a write operation, a memory block is read and, if the tracking method indicates the memory block is inverted, the write data values are inverted before being written. Inversion of data values and tracking of inverted memory blocks may be performed by a specialized memory controller or by a processor executing secure memory code. Data remanence is thus prevented in the memory.

US09323766B2 Data collection device and method
The storage allocation system reduces the amount of storage needed to store data, and also to store the most interesting dynamic data samples (e.g., waveforms). Dynamic data is relevant if it has changed from a previous sample. Changes need to be detected for different machinery conditions. The storage allocation approach normalizes static data to a percentage of danger alarm value that indicates how much the data is changing. The difference of successive percent of danger alarm values provides an instantaneous change value indicating how interesting the data is. To manage how much data is collected; the system maintains an interestingness threshold and stores data samples having an interestingness value above the threshold. The threshold is automatically adjusted if too much/little data is being saved. This approach optimizes the amount and value of data stored and data storage requirements for improved data storage efficiency.

US09323701B2 Technique for synchronizing IOMMU memory de-registration and incoming I/O data
A technique synchronizes de-registration of registered memory and incoming input/output (I/O) data received from an I/O device for storage in a memory of a computer system. Registration and de-registration of the memory with an I/O memory management unit (IOMMU) are illustratively performed by an I/O device driver of the computer system in anticipation of (or in response to) an I/O request to store the incoming I/O data in buffers of the memory. The synchronization technique ensures that storage of the I/O data in the buffers and de-registration of the buffers occur in a coordinated, reliable manner to obviate data corruption or other error conditions that may manifest in response to a race condition between such data storage and memory de-registration. Notably, I/O data which may be in-flight (i.e., inbound) from a sender to the I/O device may be received without error even when active buffers are deregistered. That is, the technique avoids handshaking with the sender before de-registering the active buffers.
