Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
127 words
A serial memory, comprising a series of memory cells, data input means, data output means, control signal input means, clock signal input means and serial address input means sharing a particular terminal with said control signal input means, characterized in that the memory is suitable for the non-shifting storage of information and furthermore comprises at least one address counter suitable for accepting, under the control of an activation signal provided by said control signal input means, a preset address accompanied by at least one of header information identifying a beginning of said preset address and termination information identifying an end of said preset address provided by said serial address input means, said at least one address counter receiving address incrementation signals from said clock signal input means.
Claim 2
Dependent Claim
127 words
A serial memory, comprising a series of memory cells, data input means, data output means, control signal input means, clock signal input means and serial address input means sharing a particular terminal with said control signal input means, characterized in that the memory is suitable for the non-shifting storage of information and furthermore comprises at least one address counter suitable for accepting, under the control of an activation signal provided by said control signal input means, a preset address accompanied by at least one of header information identifying a beginning of said preset address and termination information identifying an end of said preset address provided by said serial address input means, said at least one address counter receiving address incrementation signals from said clock signal input means.
Claim 3
Dependent Claim
42 words
A serial memory as claimed in claim 1 wherein said serial address means comprises a plurality of serial address inputs, and said memory further comprises a read address counter and a write address counter, each coupled to a respective serial address input.
Claim 4
Dependent Claim
21 words
A serial memory as claimed in claim 2, characterized in that a reset input is used as a serial address input.
Claim 5
Dependent Claim
44 words
A serial memory as claimed in claim 2, characterized in that it comprises recognition elements for header information which is preceding the preset address and is receivable on a serial address input, which header information uniquely identifies the beginning of a subsequent preset address.
Claim 6
Dependent Claim
43 words
A serial memory as claimed in claim 2, characterized in that it comprises recognition elements for termination information which succeeds the preset address and is receivable on a serial address input, which termination information uniquely identifies the end of a preceding preset address.
Claim 7
Dependent Claim
15 words
A picture memory device comprising at least one serial memories as claimed in claim 2.
Claim 8
Dependent Claim
19 words
A reproduction apparatus comprising a picture memory device as claimed in claim 6 and also comprising a reproduction element.
Claim 9
Dependent Claim
61 words
A serial memory as claimed in claim 2, characterized in that it comprises recognition elements for header information which precedes the preset address and termination information which succeeds the preset address, said information being both receivable on a serial address input, said header information and termination information together uniquely identifying the beginning and the end of a preset address, situated therebetween.
Claim 10
Dependent Claim
22 words
A serial memory as claimed in claim 1, characterized in that a reset input is used as the serial address input means.
Claim 11
Dependent Claim
15 words
A picture memory device comprising at least one serial memories as claimed in claim 9.
Claim 12
Dependent Claim
19 words
A reproduction apparatus comprising a picture memory device as claimed in claim 10 and also comprising a reproduction element.
Claim 13
Dependent Claim
45 words
A serial memory as claimed in claim 1, characterized in that it comprises recognition elements for header information which is preceding the preset address and is receivable on the serial address input means, which header information uniquely identifies the beginning of a subsequent preset address.
Claim 14
Dependent Claim
56 words
A serial memory as claimed in claim 12, characterized in that said recognition elements comprise an output via which, after detection of a given pattern in said header information by said recognition elements, a signal is supplied which disables the function of said control input means until the inspection of said preset address has been completed.
Claim 15
Dependent Claim
15 words
A picture memory device comprising at least one serial memories as claimed in claim 13.
Claim 16
Dependent Claim
19 words
A reproduction apparatus comprising a picture memory device as claimed in claim 14 and also comprising a reproduction element.
Claim 17
Dependent Claim
15 words
A picture memory device comprising at least one serial memories as claimed in claim 12.
Claim 18
Dependent Claim
19 words
A reproduction apparatus comprising a picture memory device as claimed in claim 16 and also comprising a reproduction element.
Claim 19
Dependent Claim
44 words
A serial memory as claimed in claim 1, characterized in that it comprises recognition elements for termination information which succeeds the preset address and is receivable on the serial address input means, which termination information uniquely identifies the end of a preceding preset address.
Claim 20
Dependent Claim
15 words
A picture memory device comprising at least one serial memories as claimed in claim 18.
Claim 21
Dependent Claim
19 words
A reproduction apparatus comprising a picture memory device as claimed in claim 19 and also comprising a reproduction element.
Claim 22
Dependent Claim
59 words
A serial memory as claimed in claim 1, characterized in that it comprises recognition elements for header information which precedes the preset address and termination information which succeeds the preset address, said information being both receivable on the serial address input means, said header information and termination information together uniquely identifying the beginning and the end of a preset.
Claim 23
Dependent Claim
56 words
A serial memory as claimed in claim 2, characterized in that said recognition elements comprise an output via which, after detection of a given pattern in said header information by said recognition elements, a signal is supplied which disables the function of said control input means until the inspection of said preset address has been completed.
Claim 24
Dependent Claim
15 words
A picture memory device comprising at least one serial memories as claimed in claim 21.
Claim 25
Dependent Claim
19 words
A reproduction apparatus comprising a picture memory device as claimed in claim 23 and also comprising a reproduction element.
Claim 26
Dependent Claim
15 words
A picture memory device comprising at least one serial memories as claimed in claim 1.
