Abstract: A method and device is provided for performing rotate operations on operands having a size of 2N bits, alternatively, for performing rotate operations on two operands each having a size of N bits to the left, whereby N is an integer. The device includes a control unit being adapted for exchanging M least significant bits of the output of a first rotate circuit with M least significant bits of the output of a second rotate circuit, when M =N is true, whenever an input having the width of 2N is to be rotated by M bits. For rotator arrays rotating N bit wide data to the right, it functions correspondingly.

Abstract: PROBLEM TO BE SOLVED: To provide a new method restoring a bit line and a data line from a memory cell. SOLUTION: All bit lines (510, 511) and all data lines (517, 518) are connected during a restoration operation, and all restored FET (503, 504, 505) are used for supplying a required recharging current. Successively a non-address specified bit line is turned off by its bit switch. Thus, a size of a recharging device can be made considerably small.

Abstract: A new method is indicated for the restore of bitlines and datalines from memory-cells. All bit- and datalines are switched together during the restore activity so that all restore-FETs can be prepared with the necessary re-charging current. The non-addressed bitlines are then switched off through their bitswitches. In this manner, the dimensions of the re-charging devices can be considerably reduced.
