Differential vector storage for dynamic random access memory

Mohammad Amin Shokrollahi, Harm Cronie

A storage device stores data in groups of memory cells using vectors corresponding to voltage code codewords, each codeword having k entries. Entries have values selected from a set of at least three entry values and 2.sup.n distinct inputs can be encoded ...

Methods are disclosed for creation of vector signaling codes having reduced or minimized electromagnetic emissions when transmitted over multiple conductor communications media such as microstrip channels. Particular code formulation constraints are shown ...

2016

An efficient communications apparatus is described for a vector signaling code to transport data and optionally a clocking signal between integrated circuit devices. Methods of designing such apparatus and their associated codes based on a new metric herei ...

In a high-impedance communications interface, driver energy consumption is proportional to the number of signal transitions. For signals having three or more distinct levels, it is possible for a signal driver to salvage energy from some downward signal tr ...

2016

Systems and methods are described for transmitting data over physical channels to provide a high speed, low latency interface such as between a memory controller and memory devices. Controller-side and memory-side embodiments of such channel interfaces are ...

2016

Advanced detectors for vector signaling codes are disclosed which utilize multi-input comparators, generalized on-level slicing, reference generation based on maximum swing, and reference generation based on recent values. Vector signaling codes communicat ...

2016

Multi-drop communications channels can have significantly deep notches in their frequency response causing a corresponding limitation of the effective data transmission rate. A special time-ordered coding method is described which results in the emitted sp ...

Orthogonal differential vector signaling codes with embedded clock

Mohammad Amin Shokrollahi

Orthogonal differential vector signaling codes are described which support encoded sub-channels allowing transport of distinct but temporally aligned data and clocking signals over the same transport medium. Embodiments providing enhanced LPDDR interfaces ...
