Abstract
In accordance with one embodiment, a method for accessing a memory is provided, including carrying out a first access to the memory and charging, for a memory cell, a bit line coupled to the memory cell to a value which is stored or to be stored in the memory cell, holding the state of the bit line until a second access, which follows the first access, and outputting the held state if the second access is a read access to the memory cell.
Claims16
A method for accessing a memory, the method comprising:
- carrying out a first access to the memory and charging, for a memory cell, a bit line coupled to the memory cell to a value which is stored or to be stored in the memory cell;
- storing the state of the bit line on the bit line itself by a circuit realizing a bit-line latch until a second access, which follows the first access;
- wherein the bit line is a latch node of a bit line latch;
- wherein the bit-line latch is coupled to the memory cell;
- and
- outputting the held state if the second access is a read access to the memory cell.

A memory access circuit, comprising:
- a bit line control circuit designed, in the event of a first access to a memory being carried out for a memory cell of the memory, to charge a bit line coupled to the memory cell to a value which is stored or to be stored in the memory cell;
- a storing circuit designed to store a state of the bit line on the bit line itself by a circuit realizing a bit-line latch until a second access, which follows the first access;
- where the bit line is a latch node of a bit line latch;
- wherein the bit-line latch is coupled to the memory cell;
- and
- an output circuit designed to output the held state if the second access is a read access to the memory cell.
