Abstract
Abstract An information storage arrangement is described in which the storage functions can readily be monitored. The storage comprises a plurality of functionally autonomous storage blocks. The blocks are connected to common supply lines, over which signals corresponding to the function being monitored are carried. A first verifier circuit is connected to the common supply lines following the point at which the last storage block is connected to these supply lines. The storage blocks are constructed to individually store only such small portions of the stored information that functional errors occurring in a storage block or the individual lines supplying it from the common supply lines affect only small parts of the total stored information. The portion of the stored information affected is so small that errors from individual storage blocks, or their individual circuitry, do not compensate one another, so that an error will not go undetected by a second verifier connected to each of the output lines from the individual storage blocks.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
223 words
A storage arrangement for facilitating the monitoring of storage functions, comprising: a plurality of storage blocks, each of which functions autonomously, at least as to the functions to be monitored, a plurality of common information supply lines, a plurality of individual supply lines connecting each of said storage blocks to said common supply lines in a parallel arrangement, first verifier circuit means connected to said common supply lines after the last of the connections of said individual supply lines to said common supply lines, for detecting the presence of erroneous information signals on said common supply lines, a plurality of output lines, one of which is connected to an output terminal of each said storage block and second verifier circuit means connected to each of said output lines for detecting errors occurring in at least one of said individual supply lines or in at least one of said storage blocks, each said storage block being formed to store a sufficiently small portion of the total information stored in said storage arrangement such that individual errors occurring in said storage blocks or in said individual supply lines or a combination of the two will not compensate one another, because the errors are a sufficiently small part of the total information stored, and thereby the aforementioned errors are detectable by said second verifier circuit means.
Claim 2
Dependent Claim
223 words
A storage arrangement for facilitating the monitoring of storage functions, comprising: a plurality of storage blocks, each of which functions autonomously, at least as to the functions to be monitored, a plurality of common information supply lines, a plurality of individual supply lines connecting each of said storage blocks to said common supply lines in a parallel arrangement, first verifier circuit means connected to said common supply lines after the last of the connections of said individual supply lines to said common supply lines, for detecting the presence of erroneous information signals on said common supply lines, a plurality of output lines, one of which is connected to an output terminal of each said storage block and second verifier circuit means connected to each of said output lines for detecting errors occurring in at least one of said individual supply lines or in at least one of said storage blocks, each said storage block being formed to store a sufficiently small portion of the total information stored in said storage arrangement such that individual errors occurring in said storage blocks or in said individual supply lines or a combination of the two will not compensate one another, because the errors are a sufficiently small part of the total information stored, and thereby the aforementioned errors are detectable by said second verifier circuit means.
Claim 3
Dependent Claim
50 words
The storage arrangement defined in claim 1 wherein the number of said storage blocks corresponds to the number of bits in each of the words to be stored, each of said storage blocks having capacity in bits equal to the number of words to be stored in the storage arrangement.
Claim 4
Dependent Claim
49 words
The storage arrangement defined in claim 2 wherein said storage blocks are formed into a number of groups and further comprising: individual decoder means coupled to each said storage block group for selection of a storage block in that group according to information received on said common supply lines.
Claim 5
Dependent Claim
70 words
The storage arrangement defined in claim 2 wherein said storage blocks are formed into groups and further comprising: central decoder means connected to each of said storage block groups for selecting corresponding storage blocks in each group responsive to information on said common supply lines and third verifier circuit means connected to said central decoder for detecting errors in information transmitted from said central decoder to said storage block groups.
Claim 6
Dependent Claim
129 words
The storage arrangement defined in claim 1 wherein said storage blocks are formed into a plurality of groups, wherein each said storage block stores a number b bits and wherein the number of storage block groups (m) times the number of bits (b) in each said storage block yields as a product the total number of bits in a storage word, each said storage block group having a number a of storage blocks and each said storage block storing a number n of words, the product of a times n being the total number of words in said storage arrangement and further comprising: individual decoder means connected to each said storage block group for selecting a storage block in the group responsive to information on said common supply lines.
Claim 7
Dependent Claim
134 words
The storage arrangement defined in claim 1 wherien said storage blocks are formed into a number m of storage block groups, each said storage block being adapted to store a number b of bits, the product of b times m yielding the number of bits in a storage word, and wherein each said group has a number a of storage blocks, each said storage block having a capacity of n storage words, the product of a times n yielding the word capacity of said storage arrangement and further comprising: central decoder means connected to each said storage block group for selecting a corresponding storage block in each group and third verifier circuit means connected to said central decoder means for detecting errors in information transmitted from said central decoder to said storage block groups.
