No. They're memory cells. What they're holding is state, not necessarily charge.
Don't worry about the hardware implementation, because there's more than
one way to do it. You can build a memory cell out of a pair of NAND
gates, for example (free of charge!). Or you can build it out of
ferrite cores (no charge there, either), or pulses of light (look ma!
no charge!). Just don't think about it unless you really really care.
