Abstract
The segmented word line architecture has two master word lines, to which sub-word lines are alternately allocated. Two memory banks can thus be alternately assigned to the sub-word lines.
Claims4
A segmented word line architecture for dividing up a word line into a plurality of memory banks for memory cell arrays having long bit lines, comprising:
- a plurality of memory banks respectively having a first logic state or a second logic state;
- a first master word line which can be decoded out using address bits to form a plurality of sub-word lines;
- a second master word line which can be decoded out identically to said first master word line to form a plurality of sub-word lines;
- said first and second master word lines in a memory cell array being associated to form a respective master word line pair;
- and
- said first master word line being connected via said sub-word lines thereof to said memory banks having the first logic state, and said second master word line being connected via said sub-word lines thereof to said memory banks having the second logic state, such that said memory banks having the first and the second logic state are accommodated alternately in a word line direction.
