Title: Controlling the voltage level on the word line to maintain performance and reduce access disturbs
Inventor: CHARAFEDDINE KENZA
IPC: G11C11/417
Filed: 2013-11-13
Abstract: A semiconductor memory storage data device and method of use (e.g SRAM) comprising: a plurality of storage cells 65 having port access control device(s) 60 responsive to an access control line (wordline WL); access control (word control) circuitry comprising switching circuitry (30,fig 2) configured to connect a selected access control line to one or more voltage sources (VDDB, VDDS) and feedback circuitry (inverter 50) configured to feedback a change in voltage on the access control line (WL) to the access switching circuitry 52,40,45. The access control circuitry is configured to respond to a data access request Xp to access a selected storage cell 65. This involves controlling the access switching circuitry to provide a low impedance connection (e.g MOSFET devices 40, 45 on) between the voltage source (VDDB, VDDS) and the access control line (WL) such that a voltage level on the access control line (WL) changes towards the predetermined access voltage level at a first rate; and in response to the feedback circuitry (50) providing a feedback signal indicating that the access control line voltage has attained a predetermined (threshold) value to control the access control switching circuitry to provide a higher impedance connection (only MOSFET device 45 on) between the voltage source and the access control line, such that a voltage level on the access control line WL changes towards the predetermined access voltage level for devices 60 at a second rate, the second rate being slower than the first rate. Hence a dual slope or double gradient is observed on the word line during memory cell activation. FinFET transistors may be used in the memory storage devices.

Title: (Nx2)-channel bit communication system
Inventor: ALKHALED FAHAD S H Z
IPC: H04L29/06
Filed: 2013-11-20
Abstract: A binary communication system is described with two channels (or multiples of pairs of channels) wherein one of the channels is exclusively used to convey logic 1 and the other to convey logic 0 states. A receiver listens to the two channels and determines whether a binary 1 (one) or 0 (zero) has been received by performing a comparison of the energy of the respective paths/channels related to each state. The information is transmitted as bit pulses over the communication medium. The actual medium can be wired or wireless and is only constrained by the two (or each pair of) channels being identical. For example, at a given time, any pulse transmitted and received through the first channel represents logic one, while any pulse transmitted and received through the second channel represents logic zero. Having dedicated channels is said to lower the bit error rate to close to, or equal to, zero. A re-calibration stage may also be periodically undertaken wherein pulses are simultaneously sent on both channels (i.e. a 1 and 0 are simultaneously sent) to correct the clocks based on differences in times of arrival over the pair of channels and/or to correct the threshold (attenuation factor) used for comparison of the channels energies.
