31. CTLs and NK cells are both memory cells for long term resistance toward tumor cells. 32. Thinfilm's patented passive matrix dispenses with the need of active circuitry within the memory cell . 33. NOR and NAND flash get their names from the structure of the interconnections between memory cells . 34. Operations are free except to access memory cells . 35. Memory chips contain millions of memory cells -- one for each bit of information they can store. 36. Memory cells held signed decimal numbers from 0 to ?99 and were written with a pencil.37. Again, there is a positive feedback but now it is concentrated only in the memory cell . 38. Usually several memory cells share the same address. 39. Erasing the NOR Flash memory cell removes stored charge through the process of Fowler Nordheim tunneling. 40. In this model, computation is framed as a problem of querying a set of memory cells .
