A volatile memory includes volatile memory cells in which data write and read operations are performed. The memory cells are arranged in rows and in columns and are distributed in first separate groups of memory cells for each column. The memory includes, for each column, a write bit line dedicated to write operations and connected to all the memory cells of the column and read bit lines dedicated to read operations. Each read bit line is connected to all the memory cells of one of the first groups of memory cells. Each memory cell in the column is connected to a single one of the read bit lines.

Volatile memory with a decreased consumption and an improved storage capacity

A volatile memory including volatile memory cells adapted to the performing of data write and read operations. The memory cells are arranged in rows and in columns and, further, are distributed in separate groups of memory cells for each row. The memory includes a first memory cell selection circuit configured to perform write operations and a second memory cell selection circuit, different from the first circuit, configured to perform read operations. The first circuit is capable of selecting, for each row, memory cells from one of the group of memory cells for a write operation. The second circuit is capable of selecting, for each row, memory cells from one of the groups of memory cells for a read operation.
