    摘要: An address strobe latches a first address. A burst cycle increments the address internally with additional address strobes. A new memory address is only required at the beginning of each burst access. Read/Write commands are issued once per burst access eliminating toggling Read/Write control line at cycle frequency. Control line transition terminates access and initializes another burst access. Write cycle times are maximized thereby allowing increases in burst mode operating frequencies. Logic near sense amplifiers control write-data drivers thereby providing maximum write times without crossing current during I/O line equilibration. By gating global write-enable signals with global equilibrate signals locally at sense amps, local write-cycle control signals are provided and valid for essentially the entire cycle time minus an I/O line equilibration period in burst access memory. For nonburst mode, write begins following end of equilibration cycle to provide maximum write time without interfering with subsequent access-cycle address setup time.

    摘要: Expect data signals are generated for a series of applied data signals having a known sequence to determine if groups of the data signals were properly captured. A first group of the applied data signals is captured, and a group of expect data signals are generated from the captured first group. A second group of applied data signals is then captured and determined to have been properly captured when the second group corresponds to the group of expect data signals. In this way, when a captured series of data signals is shifted in time from an expected capture point, subsequent captured data signals are compared to their correct expected data signals in order to determine whether that group, although shifted in time, was nonetheless correctly captured. A pattern generator generates expect data signals in this manner, and may be utilized in a variety of integrated circuits, such as an SLDRAM.

    摘要: An integrated device includes a redundant bond pad for accessing internal circuitry in the event that the main bond pad for that circuitry is difficult to access with testing equipment. Signals from the redundant bond pad are biased to ground during normal operations of the integrated device. In order to test the relevant internal circuitry, a voltage is applied to a Test Mode Enable bond pad, overcoming the bias that grounds the redundant bond pad. In addition, the signal from the Test Mode Enable bond pad serves to ground any transmission from the main bond pad. As a result, the redundant bond pad may be used to test the relevant internal circuitry given its accessible location in relation to the testing equipment.

    摘要: An integrated circuit memory device is designed to perform high speed data write cycles. An address strobe signal is used to latch a first address. During a burst access cycle the address is incremented internal to the device with additional address strobe transitions. A new memory address is only required at the beginning of each burst access. Read/Write commands are issued once per burst access eliminating the need to toggle the Read/Write control line at the device cycle frequency. A transition of the Read/Write control line during a burst access is used to terminate the burst access and initialize the device for another burst access. Write cycle times are maximized to allow for increases in burst mode operating frequencies. Local logic gates near a nay sense amplifiers are used to control write is data drivers to provide for maximum write times without crossing current during input/output line equilibration periods. By gating global write enable signals with global equilibrate signals locally at data sense amp locations, local write cycle control signals are provided which are valid for essentially the entire cycle time minus an I/O line equilibration period in burst access memory devices. For nonburst mode memory devices such as EDO and Fast Page Mode, the write function may begin immediately following the end of the equilibration cycle to provide a maximum write time without interfering with the address setup time of the next access cycle.

    摘要: A command buffer for use in packetized DRAM includes a four stage shift register for shifting for sequentially storing four 10-bit command words. The shift register combines the four 10-bit command words into a single 40-bit command word and transfer the 40-bit command word to a storage register for processing by the DRAM. The shift register may then continue to receive and store subsequent 10-bit command words. The command buffer also includes circuitry for determining whether a command packet is intended for the memory device containing the command buffer or whether it is intended for another memory device. Specifically, a portion of the 40-bit command word from the storage register is compared to identifying data stored in an identifying latch. In the event of a match, a chip select signal is generated to cause the memory device to perform the function corresponding to other portions of the 40-bit command word. The identifying latch is programmed with the unique identifying data during power-up by storing the identifying data responsive to an initialization command packet. The shift register includes shift register circuits that are specifically adapted to operate at very high speeds.

    摘要: A balanced switching circuit comprises a plurality of transfer gates, each transfer gate having an input terminal, an output terminal, and at least one control terminal adapted to receive a control signal. Each transfer gate, which may be comprised of pass transistors such as n- and p-channel metal oxide semiconductor (MOS) transistors, is operable to couple the input terminal to the output terminal in response to the control signal. The plurality of transfer gates are arranged in N rows and N columns with the input and output terminals of the N transfer gates in each row connected in series between a first signal terminal and a second signal terminal. Each transfer gate has its control terminal connected to one of N clock terminals adapted to receive respective clock signals. Each clock terminal is coupled to the control terminal of only one transfer gate in each row and only one transfer gate in each column. The balanced transfer gate circuit is operable to couple the first signal terminal to the second signal terminal in response to the clock signals. The transfer gates are selectively clocked or activated such that the switching speed is independent of the order in which the individual series connected past transistors or transfer gates are activated. A shift register circuit, a memory device, and a computer system utilizing such a balanced switching circuit are also described.
