摘要： Aspects of the invention may be found in a method and system for testing an integrated circuit and may comprise an address selector, data selector and staging register coupled to a signal generator. The address selector may comprise a direct access memory test (DAMT) mode address control input and one or more output address pins coupled to an embedded memory device under test (DUT). The data selector may be coupled to at least one data pin and control pin of the signal generator and may comprise a DAMT mode data control input and at least one data output coupled to embedded memory DUT. A staging register comprising a first output clock rate which is one-quarter (¼) its input clock rate and matches a DUT burst write frequency may be coupled to an input of the data selector. A DAMT mode control may configure the memory DUT for DAMT operation.

摘要： Methods and systems for hardware controlling of an electrically erasable programmable read only memory (EEPROM) are described herein. Aspects of the invention may include generating a clock signal at a frequency suitable for EEPROM operation and resetting an EEPROM utilizing the generated clock signal and a hardware generated data signal without initiation by a central processing unit (CPU). The resetting may occur via a virtual CPU. The CPU and the virtual CPU may be integrated on a single chip. The signal generation and EEPROM resetting may occur via a virtual CPU integrated within a finite state machine. A frequency counter may be utilized to generate a clock signal from a clock source having a higher frequency than that required by the EEPROM.

摘要： Automatically detecting types of external FLASH devices is provided, and may comprise communicating one or more read memory device ID commands corresponding to at least one supported memory device to at least one memory device. Data received in response to this communication may be utilized to determine whether the received data identifies the memory device as one of the plurality of supported memory devices. The supported memory devices may be serial FLASH memory devices. Each read memory device ID command may be manufacturer specific, or may be specific to a group of the supported memory devices. The communicating of read memory device ID commands and determining whether the memory device is a supported memory device may be repeated if the memory device is not identified as one of the supported memory devices. There may be a limit to the number of times this is repeated.
