Disclosed are embodiments of a built-in self-test (BIST) architecture that incorporates a standalone controller that operates at a lower frequency to remotely perform test functions common to a plurality of embedded memory arrays. The architecture also incorporates command multipliers that are associated with the embedded memory arrays and that selectively operate in one of two different modes: a normal mode or a bypass mode. In the normal mode, instructions from the controller are multiplied so that memory array-specific test functions can be performed locally at the higher operating frequency of each specific memory array. Whereas, in the bypass mode, multiplication of the instructions is suspended so that memory array-specific test functions can be performed locally at the lower operating frequency of the controller. The ability to vary the frequency at which test functions are performed locally, allows for more test pattern flexibility.

Non-volatile memory devices and arrays are described that facilitate the use of band-gap engineered gate stacks with asymmetric tunnel barriers in reverse and normal mode floating node memory cells in NOR or NAND memory architectures that allow for direct tunnel programming and erase, while maintaining high charge blocking barriers and deep carrier trapping sites for good charge retention. The low voltage direct tunneling program and erase capability reduces damage to the gate stack and the crystal lattice from high energy carriers, reducing write fatigue and enhancing device lifespan. The low voltage direct tunnel program and erase capability also enables size reduction through low voltage design and further device feature scaling. Memory cells of the present invention also allow multiple bit storage. These characteristics allow memory device embodiments of the present invention to operate within the definition of a universal memory, capable of replacing both DRAM and ROM in a system.

A computer system operates in normal mode where all applications and files are accessible to an authorized user, where an authorized user enters a required log in to access all applications. When a trigger to change the control access from normal mode to selective lock mode is detected, access to the applications and files is blocked and the content within the user interface is cleared to initiate the selective lock mode. Next, content is added to the user interface including a folder with only a selection of the applications each accessible through a separate selectable link, where the selectable links are designated in the particular folder by an authorized user during normal mode. During selective lock mode, any user may only select to open one of the selection of applications by selecting a displayed selectable link for the application.

In a portable biological information monitor apparatus, a pulse wave detection signal obtained by light emission from a green LED and a body motion detection signal obtained by light emission from an infrared LED are detected as biological information. This biological information is analyzed to compute various barometers. In a wake normal mode of a set generation mode, body motion and pulse are calculated as wake evaluation barometers for evaluation of a test subject's status in wake. In a wake steady state motion mode, body motion, pulse, and pitch are calculated as motion evaluation barometers for evaluation of the test subject's status in steady state motion. In a sleep mode, body motion, pulse, and autonomic nervous function are calculated as sleep evaluation barometers for evaluation of the test subject's status in sleep. Necessary barometers are thereby generated regardless of the test subject's action using the portable monitor apparatus alone.

Storage elements are read multiple times and the results are accumulated and averaged for each storage element to reduce the effects of noise or other transients in the storage elements and associated circuits that may adversely affect the quality of the read. Several techniques may be employed, including: A full read and transfer of the data from the storage device to the controller device for each iteration, with averaging performed by the controller; a full read of the data for each iteration, with the averaging performed by the storage device, and no transfer to the controller until the final results are obtained; one full read followed by a number of faster re-reads exploiting the already established state information to avoid a full read, followed by an intelligent algorithm to guide the state at which the storage element is sensed. These techniques may be used as the normal mode of operation, or invoked upon exception condition, depending on the system characteristics. A similar form of signal averaging may be employed during the verify phase of programming. An embodiment of this technique would use a peak-detection scheme. In this scenario, several verify checks are performed at the state prior to deciding if the storage element has reached the target state. If some predetermined portion of the verifies fail, the storage element receives additional programming. These techniques allow the system to store more states per storage element in the presence of various sources of noise.

A running mode is determined on the basis of an input mode setting signal MSW. A lower intermittence prohibition vehicle speed is set when the running mode is a power mode than when the running mode is a normal mode. When a vehicle speed is equal to or higher than the set intermittence prohibition vehicle speed, an engine is prohibited from being operated intermittently. When the vehicle speed is not equal to or higher than the intermittence prohibition vehicle speed, a vehicle runs with the engine permitted to be operated intermittently. When the power mode is set, the engine is more often prohibited from being operated intermittently and hence is more often in operation. Therefore, the responsiveness of a driving force is enhanced. Further, when the normal mode is set, the engine is more often permitted to be operated intermittently. Therefore, no deterioration in fuel economy is caused.

A system and method are disclosed for improving the remote display of graphics images by the redirection of rendering and the optional use of image data compression. Instead of sending graphics commands over a network and rendering on a remote computer system, graphics commands may be automatically redirected by modified OpenGL functions to local graphics devices without explicit involvement by the graphics application. The modifications to a set of the OpenGL functions on the local system are transparent in the normal mode of rendering and displaying locally. After an image is rendered locally, it may be read back and sent across the network. A standard X Server on the remote system may be sufficient to support this methodology. An X Extension for data decompression on the remote system, however, may allow for more efficient image transmission through the use of image data compression.
