Multi-level memory cell sensing
摘要:
The delay arising from wordline capacitance in multi-level memories may be reduced by adding switched transistors along the wordline path. Also, the wordline may be pre-charged to a high level and then the first wordline voltage level for reading may be a center level. The switched transistors may be p-devices whose n-wells are biased by a stable DC voltage. Nodes along the wordline may float when not accessed. Finally, a distributed voltage generator may be used.
