#CMT# #/CMT# A semiconductor memory module comprises an electronic printed circuit board having many similar memory chips (3) on the surface and an edge (10) contact strip (11) with a row of contacts and two neighboring rows of similar rectangular chips of shorter (a) and longer (b) dimensions above one another. The chips in one set have their shorter measurement parallel to the contact strip while those of the other set have their longer measurement parallel to the contact strip. #CMT#USE : #/CMT# As a semiconductor memory module (claimed) for DDR3-DRAM chips. #CMT#ADVANTAGE : #/CMT# Large memory chips, such as DDR3-DRAM chips, can be accommodated in two rows on the circuit board while having short and equal lead lengths. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# A plan of the arrangement is shown. 3 : Chips 10 : Edge 11 : Contact strip a,b : Chip edges. |
