ABSTRACT:
An embedded memory device is designed in such a manner that allows the embedded memory device to undergo the burn-in process more conveniently and efficiently without the need to use complex control timing. Moreover, the embedded memory device allows the burn-in board to be simpler than the prior art in layout structure. The embedded memory device includes the following: a memory unit having an address decoder and a sense amplifier; a control logic unit capable of generating an output of system data and an output of system address; a first counter which is driven by a system clock signal for generating an output of counter address; a second counter which is capable of generating an output of counter data; an address buffer, under control by a burn-in signal, for selecting either the system address or the counter address as memory address to the address decoder; and a data buffer, also under control by the burn-in signal, for selecting the counter data or the system data as memory data to the sense amplifier. The foregoing architecture for the embedded memory device allows the burn-in process to be performed more cost-effectively than the prior art.
