    摘要: A Defect Leakage Screen Test apparatus and method is introduced to eliminate or reduce steps in the failure analysis process of memory devices, such as DRAM cells, or to eliminate the necessity for the application of a physical failure analysis on the memory device. Special single bit failures due to leakage current, junction current, or threshold leakage current, are characterized by varying the p-well voltage of the memory device during the read operation of the test. The p-well voltage is varied with a test code Initial Program Load (IPL). Additional logic is provided on the memory IC to decode the IPL logic signals. In order to perform the p-well varying test, the memory device is provided with the following: IPL decoding logic; a reference voltage generator; an IPL voltage reference multiplexor; a p-well voltage feed-back circuit; and a differential amplifier circuit.

    摘要: A semiconductor memory chip architecture is described implementing of a multi-bit data control function which enables independent control of at least a plurality of data bits via a single control signal. A logically organized memory chip is organized as a 2.sup.n x 4 chip in which one control (CAS0) signal enables a single data bit and another control (CAS1) signal enables the remaining three data bits. By organizing data control on chips in this manner, it becomes possible to optimize design modules such that a minimum number of control signals are used.

    摘要: A high speed Random Access Memory (RAM) array device includes several logical banks, each of which can be uniquely addressed. Each of these logical banks contains a unique memory array segment and associated page register, the latter serving as a temporary storage location during high-speed page hit operations. To reduce latency during an initial page hit, further array optimization is realized by segmenting each logical bank into two segments with one, smaller segment, comprising a faster random access memory (FRAM) for storing initial data in a data stream. A high speed page register connects the FRAM directly to a multiplexer/demultiplexer connected to the device I/O ports bypassing an internal bus protocol such that the initial data can be transferred between the FRAM and the I/O ports faster thereby improving page-hit latency. Hence, segmenting the logical banks to include only a small high speed segment results in a performance gain approaching what could be achieved by implementing the entire memory device with a high speed FRAM, but at much lower cost.
