A memory built-in self test ('BIST') system comprises: a controller; a single port memory engine coupled to one or more single port memories; and a non-single port memory engine coupled to one or more non-single port memories. The controller receives operation codes ('op-codes') for testing a plurality of memory types. An output of the controller is coupled to inputs of the single port memory engine and the non-single port memory engine. The controller generates test instructions based on the received op-codes. The single port memory engine and the non-single port memory engine interpret the test instructions to test the one or more single port memories and the one or more non-single port memories.

Memory built-in self test system

A memory diagnostic system comprises a test engine and a miscompare logic. The test engine provides test instructions with expected data to a memory under test ('MUT'). The MUT processes such test patterns and outputs the results of such test patterns as stored data. The miscompare logic has local miscompare logics and a global miscompare logic. Each of the local miscompare logics compares a predefined range of bits of the expected data with a corresponding predefined range of bits of the stored data. One or more miscompare flags are generated for one or more miscompares determined by the local miscompare logics. The global miscompare logic monitors the one or more miscompare flags. When a total number of the miscompare flags exceeds a threshold number, the global miscompare logic generates a pause signal to the local miscompare logics to capture a current state of the local miscompare logics.

Diagnostics for a memory device

A fuse controller comprises: a fuse bay, a bus, an engine, and an interface. The fuse bay stores repair and setting information for a plurality of fuse domains in a linked-list data structure. The engine manages the linked-list data structure. The engine also is coupled to the fuse domains via the bus. The interface is coupled to the engine and receives commands and data for operating the engine.

Multi-domain fuse management

An improved tire puncturing device includes a base plate having a plurality of drive pins whose axes are formed in a plane perpendicular to the plane of the base plate. The drive pins extend from one side of the base plate and include a free end which forms a piercing point. Each of the drive pins are secured in the base plate and have an aperture formed therethrough for enabling fluid to enter the aperture at the piercing point and exit the drive pin at the other side of the base plate.

Tire puncturing device

A tire puncturing device includes a plurality of drive pins which are mounted on a base plate. The pins can be forced into an automobile tire in order to puncture the tire and thus prevent the automobile from being driven. The drive pins are normally Teflon coated in order to prevent the tire from sealing onto the pins. The device is intended primarily for law enforcement officers.
