US 11,237,828 B2 · Secure matrix space with partitions for concurrent use

Abstract

This application discloses a mechanism to securely store and compute with a matrix of numbers or any two-dimensional array of binary values in a storage entity called a matrix space. A matrix space is designed to store matrices or arrays of values into arrays of volatile or non-volatile memory cells with accessibility in two or three dimensions. Any row or column or line of storage elements in the storage entity is directly accessible for writing, reading, or clearing via row bit lines and column bit lines, respectively. The elements in rows of the arrays are selected or controlled for access using row address lines and the elements in columns of the arrays are selected or controlled for access using column address lines. Access control methods and mechanisms with keys to secure, share, lock, and unlock regions in the matrix space for matrices and arrays under the control of an operating system or a virtual-machine hypervisor by permitted threads and processes are also disclosed.

Dependent claims

A computing machine comprising:

at least one matrix space having an embedded storage comprising a first array of storage cells, wherein the embedded storage further comprises:
a plurality of row bit lines comprising a set of row values;
a plurality of row logic switches controlled by one or more row address lines;
a plurality of column bit lines comprising a set of column values;
and
a plurality of column logic switches controlled by one or more column address lines, wherein the plurality of row bit lines is coupled to the storage cells via the plurality of row logic switches, and wherein the plurality of column bit lines is coupled to the storage cells via the plurality of column logic switches;
and
logic to perform one or more operations with one or more selected column bit lines, selected row bit lines, and selected storage cells, wherein writing via the plurality of row bit lines and writing via the plurality of column bit lines occur into separate and non-intersecting selection of the selected storage cells,
wherein the at least one matrix space comprises at least one matrix region that is controlled by at least one key register.
