Matrix's first product is a memory chip—an easier design and manufacturing task than a full-blown microprocessor chip of the sort that provides the guts of a computer. _______________________________________ . That is well under a third of the price of comparable flash-memory cards. The principal disadvantage is that, unlike flash cards, it cannot be wiped clean for reuse. Matrix's chips can record data only once.
A.
But, while that solves one problem, it creates another. For making such a multistory chip is hard.
B.
But the real principal advantage of matrix's memory chip is cost. The 64 megabyte version, which can hold about two hours-worth of music, costs less than $10.
C.
For this obvious disadvantage, the multi-story chip is still under intensive research and experts say it still takes years before they are successfully marketed.
