  • Patent number: 11257534
    Abstract: Methods, systems, and devices for a current monitor for a memory device are described. A memory device may monitor potential degradation of memory cells on the device by monitoring the amount of current drawn by one or more memory cells. As the memory cells degrade, the current supplied to the memory cells may change (e.g., increase due to additional leakage current. The memory device may indirectly monitor changes in the current supplied to the memory cells by monitoring a voltage of a node of a transistor that controls the amount of current supplied to the array of memory cells. The voltage at the control node may be compared to a reference voltage to determine whether the two voltages differ by a threshold amount, indicating that the memory cells are drawing more current. The memory device may output a status indicator when the voltages differ, for example, by the threshold amount.

  • Patent number: 8631267
    Abstract: Disclosed herein are solutions for addressing the problem of skew of data within a byte lane by factors caused external to the integrated circuit or module providing the data. To compensate for such skew, an on-chip delay is added to the data out paths of those bits in the byte lane with otherwise would arrive early to their destinations. Such on-chip delay is provided delay circuits preferably positioned directly before the output buffers/bond pads of the integrated circuit or module. By intentionally delaying some of the outputs from the integrated circuit or module, external skew is compensated for so that all data in the byte lane arrives at the destination at substantially the same time. In a preferred embodiment, the delay circuits are programmable to allow the integrated circuit or module to be freely tailored to environments having different skew considerations, such as different styles of connectors.

  • Patent number: 7423339
    Abstract: An inventive electronic device, such as a multi-chip module (MCM), a Single In-line Memory Module (SIMM), or a Dual In-line Memory Module (DIMM), includes a base, such as a printed circuit board, having a surface on which flip-chip pads and wire-bondable pads are provided. The flip-chip pads define an area on the surface of the base at least partially bounded by the wire-bondable pads. A first integrated circuit (IC) die is flip-chip bonded to the flip-chip pads, and a second IC die is back-side attached to the first IC die and then wire-bonded to the wire-bondable pads. As a result, the flip-chip mounted first IC die is stacked with the second IC die in a simple, novel manner.

  • Patent number: 7414875
    Abstract: A layout for simultaneously sub-accessible memory modules is disclosed. In one embodiment, a memory module includes a printed circuit board having a plurality of sectors, each sector being electrically isolated from the other sectors and having a multi-layer structure. At least one memory device is attached to each sector, the memory devices being organized into a plurality of memory ranks. A driver is attached to the printed circuit board and is operatively coupled to the memory ranks. The driver is adapted to be coupled to a memory interface of the computer system. Because the sectors are electrically-isolated from adjacent sectors, the memory ranks are either individually or simultaneously, or both individually and simultaneously accessible by the driver so that one or more memory devices on a particular sector may be accessed at one time.

  • Patent number: 7327620
    Abstract: Disclosed herein are exemplary embodiments of an improved differential input buffer for receiving low power signals and associated methods. The disclosed buffer circuit comprises at least one differential amplifier for receiving as inputs an enable signal (e.g., a clock enable signal) and a reference signal, and provides a differential amplifier output representative of a comparison of the magnitude of the input signals. As improved, input buffer circuitry comprises a pull up stage to pull up the voltage of the differential amplifier output slightly higher during an output low condition. The pull up stage is preferably, but not necessarily, activated only during a problematic condition, such as when both input signals to the differential amplifier are low. By pulling up the output, the input buffer circuit enjoys improved margin, and is able to reliably signal a low power condition even when both inputs are low.

  • Patent number: 6807613
    Abstract: Some synchronous semiconductor memory devices accept a command clock which is buffered and a write clock which is unbuffered. Write command are synchronized to the command clock while the associated write data is synchronized to the write clock. Due to the use of the buffer, an arbitrary phase shift can exist between the command and write clocks. The presence of the phase shift between the two clocks makes it difficult to determine when a memory device should accept write data associated a write command. A synchronous memory device in accordance with the present invention utilizes the unbuffered strobe signal which is normally tristated during writes as a flag to mark the start of write data. A preamble signal may be asserted on the strobe signal line prior to asserting the flag signal in order to simplify flag detection.

  • Patent number: 6638807
    Abstract: An improved structure and method for gated lateral bipolar transistors are provided. Embodiments of the present invention capitalize on opposing sidewalls and adjacent conductive sidewall members to conserve available surface space on the semiconductor chips. Additionally, the gate and body of the transistors are biased to modify the threshold voltage of the transistor (Vt). The conductive sidewall member configuration conserves surface space and achieves a higher density of surface structures per chip. The structures offer performance advantages from both metal-oxide semiconductor (MOS) and bipolar junction transistor (BJT) designs. The devices can be used in a variety of applications, digital and analog, wherever a more compact structure with low power consumption and fast response time is needed.

  • Patent number: 5849624
    Abstract: Disclosed is an improved stacked capacitor with rounded corners for increasing capacitor breakdown voltage, and a method of constructing the same. The preferred method comprises rounding corners of a container-shaped bottom electrode. In particular, sharp corners of a pre-fabricated conductive silicon container are exposed to an ammonium hydroxide/peroxide mixture. The slow etching effect of the clean rounds angled surfaces thereby minimizing the high field effects usually associated with corners and other angled surfaces. Reducing such field effects by reducing or eliminating sharp corners helps prevent breakdown of the capacitor structure dielectric. Where the conductive container includes a rough layer, such as hemispherical grained silicon, the invention provides the additional advantage of separating individual hemispherical grains, thus allowing later deposition of a uniformly thick dielectric layer.
