Map the Mostek vs Ti Competitive Landscape

# Map the Mostek-versus-TI Competitive Landscape

With the MK4096 and the TMS4030 both on the market, the 4K DRAM generation became a direct commercial contest between Mostek and Texas Instruments for design-win share.

System houses evaluated both parts against price, availability, second-source options, and timing margins, rather than defaulting to whichever single supplier had shipped a 1K part first.

This competitive pressure between the two leading suppliers is part of why the 4K generation moved prices down and volumes up quickly, setting the commercial pattern that later DRAM generations would repeat at every density step.
