Abstract
Abstract A MOS storage module has MOS transistor storage cells disposed between word and bit lines. A weighting network is symmetrically connected in each pair of bit lines for evaluating read signals. The weighting networks are arranged in a column with the storage cells which are connected to first inputs of the weighting networks form a first storage cell field and the storage cells which are connected to second inputs of the weighting networks form a second storage cell field and all storage cell fields on the storage module are disposed on one side of the column of weighting networks.
