Abstract
Abstract An address designating method of a memory is performed by dividing the addresses of the memory to row addresses and column addresses. The writing of data in the memory is performed by the following steps. Namely, while the row addressing is maintained in a predetermined value (for example, 7d+1), the column addressing is incremented one by one. When the column addressing reaches 3, the row addressing is decremented by 4d+1. Each time the row addressing is decremented by d, the column addressing is decremented one by one in accord therewith. The reading of the data from the memory is performed by the following steps. Namely, each time the row addressing is incremented by d, the column addressing is also incremented one by one in accord therewith. When the column addressing reaches 3, the row addressing is decremented by 3d+1. With the row addressing kept in 0, the column addressing is decremented one by one.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
225 words
A method of designating addresses of a memory by dividing the addresses of the memory into row addresses of row addressing and column addresses of column addressing, said method comprising the steps of, on the occasion of the writing of the data in said memory, adding a predetermined integer value B in succession to said column addressing by maintaining said row addressing in a predetermined positive integer value A, subtracting a predetermined integer value D from said row addressing responsive to reaching of said column addressing to a predetermined positive integer value C, and subtracting in succession a predetermined integer value B from said row addressing while subtracting said predetermined integer value B in succession from said column addressing in accord therewith, and on the occasion of the reading of the data from said memory, adding said predetermined integer value E in succession to said row addressing obtained by subtracting a predetermined integer value F from said predetermined integer value A, while adding said predetermined integer value B in succession to said column addressing in accord therewith, subtracting a predetermined integer value G from said row addressing responsive to reaching of said column addressing to said predetermined integer value C, and subtracting said predetermined integer value B in succession from said column addressing by maintaining said row addressing in a predetermined positive integer value H.
Claim 2
Independent Claim
