Abstract
In a random access memory, a sequence of selection signals for a combined multi-memory operating functionality is supplied on control lines which connect the control logic to each memory cell in a cell field when the memory is in a combined multi-memory operating mode, and a sequence of selection signals for the write enable functionality is supplied when the memory is in the single-memory operating mode.
Claims6
A method for alternate operation of a random access memory in single-memory operating mode and in combined multi-memory operating mode, which comprises the following method steps:
- when an operating mode signal indicates a combined multi-memory operating mode, supplying a sequence of selection signals for a combined multi-memory operating functionality on control lines connecting a control logic to respective memory cells in a cell field;
- and
- when the operating mode signal indicates a single-memory operating mode, supplying a sequence of masking signals for a write enable functionality.
A random access memory, comprising:
- a cell field with a plurality of memory cells;
- a control logic;
- and
- control lines connecting said control logic to each said memory cell in said cell field;
- said control logic supplying, on said control lines, a sequence of selection signals for a combined multi-memory operating functionality to said memory cells when the memory is in a combined multi-memory operating mode, and supplying a sequence of masking signals for the write enable functionality to said memory cell when the memory is in a single-memory operating mode.
