Abstract
Abstract A data storage and retrieval system which in a preferred embodiment thereof uses at least two integrated circuit units each having a plurality of storage registers and appropriate data access and data insertion means thereon. The same data is stored in corresponding storage registers in each integrated circuit unit so that simultaneous access can be obtained to data in two or more storage devices for supplying such data simultaneously to a data processing unit. Data received from a data processing unit can also be simultaneously stored in appropriately corresponding data registers of each integrated circuit unit.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
213 words
Data storage and retrieval means for providing simultaneous access to data stored in more than one data storage device to make said data available for use, said data storage and retrieval means comprising first means including a plurality of first storage devices for storing data; first data selection means for providing access to the data in at least a selected one of said first storage devices at one time to make the data from said selected one of said first storage devices available; and at least one additional means, each said additional means including a plurality of additional storage devices for storing data, at least some of said plurality of additional storage devices storing the same data as that stored in at least some of said plurality of first storage devices, additional data selection means operable independently of said first data selection means for providing access to the data in any selected one of said additional storage devices at one time to make the data from said selected one of said additional storage devices available simultaneously with the data from said selected one of said first storage devices; and means for controlling the operations of said first and said additional data selection means whereby the data accessed thereby is simultaneously available for use.
Claim 2
Dependent Claim
213 words
Data storage and retrieval means for providing simultaneous access to data stored in more than one data storage device to make said data available for use, said data storage and retrieval means comprising first means including a plurality of first storage devices for storing data; first data selection means for providing access to the data in at least a selected one of said first storage devices at one time to make the data from said selected one of said first storage devices available; and at least one additional means, each said additional means including a plurality of additional storage devices for storing data, at least some of said plurality of additional storage devices storing the same data as that stored in at least some of said plurality of first storage devices, additional data selection means operable independently of said first data selection means for providing access to the data in any selected one of said additional storage devices at one time to make the data from said selected one of said additional storage devices available simultaneously with the data from said selected one of said first storage devices; and means for controlling the operations of said first and said additional data selection means whereby the data accessed thereby is simultaneously available for use.
Claim 3
Dependent Claim
32 words
A data storage and retrieval means in accordance with claim 1 wherein all of said additional storage devices store the same data as is stored in all of said first storage devices.
Claim 4
Dependent Claim
24 words
A data storage and retrieval means in accordance with claim 1 wherein said first means and each of said additional means are integrated circuits.
Claim 5
Dependent Claim
35 words
Data storage and retrieval means in accordance with claim 3 wherein There is only one additional integrated circuit means whereby data is supplied simultaneously to said data processing unit from both said integrated circuit means.
Claim 6
Dependent Claim
59 words
Data storage and retrieval means in accordance with claim 1 and further including first data insertion means for receiving data and for inserting said data into a selected one of said first storage devices; and additional data insertion means for receiving the same said data and for inserting said data into a selected one of said additional storage devices.
Claim 7
Dependent Claim
28 words
Data storage and retrieval means in accordance with claim 5 wherein said controlling means further controls the operations of said first and each said additional data insertion means.
Claim 8
Dependent Claim
83 words
Data storage and retrieval means in accordance with claim 5 wherein said first data selection means, said first data insertion means, and said plurality of first storage devices are integrated circuits formed on the same integrated circuit chip and the data selection means, the data insertion means, and the plurality of storage devices of each additional means are integrated circuits formed on the same integrated circuit chip, each of said integrated circuit chips being separate from each other of said integrated circuit chips.
Claim 9
Dependent Claim
35 words
Data storage and retrieval means in accordance with claim 7 wherein said first storage devices and each of said plurality of additional storage devices are formed in at least one 4 X 4 matrix configuration.
Claim 10
Dependent Claim
33 words
Data storage and retrieval means in accordance with claim 8 wherein said first storage devices and each of said plurality of additional storage devices are formed in a 4 X 16 matrix configuration.
