CXMT's 4F² DDR5 Memory Plan To 'Leapfrog' Samsung & Others By Two Years Is A Paper Tiger, Say Analysts, As Sanctions Push It Into Bitter…

Chinese memory chip manufacturer CXMT's recent claim that it would 'leapfrog' established memory giants Samsung, SK hynix and Micron by two years is nothing but that of a paper tiger, analysts from Rosenblatt believe. CXMT's President, Dr. Cao Kanyu, recently claimed at the…

Note: Standard designs, which are referred to as 6F², have transistors, also referred to as pillars, staggered in an offset grid pattern between the bit and word lines. On the other hand, 4F² optimizes the design by placing the pillars over the interesting bit and word lines to reduce the area of the memory cell. The reason 4F² is able to reduce the area is through vertically stacking the bit line…

The reason 4F² is able to reduce the area is through vertically stacking the bit line contacts, capacitors and transistors which are otherwise laid out horizontally in a 6F² cell design.
