Compare Tms4030 Design Choices to Mk4096

# Compare TMS4030 Design Choices to the MK4096

The TMS4030 reached 4K density using TI's own cell and sense-amplifier design choices, which differed from Mostek's in process detail even though both parts landed on the same multiplexed-addressing concept.

Differences between the two parts showed up in access speed, power consumption, and exact pin assignments, giving system designers a genuine choice rather than two interchangeable clones.

That both companies converged on multiplexed RAS/CAS addressing independently, while differing in the underlying cell engineering, is strong evidence that multiplexing was the necessary fix for this density tier rather than one company's proprietary trick.
