There may not be a major target market. SRAM is one of the easiest kinds of chips to make- very regular patterning, doesn't need an army of engineers to design... so it could be a launch vehicle whose primary goal is to flush out the design & manufacturing process, with other chips to follow.
The 6T cell is also a critical building block to many kinds of chips, and it in itself can be hard to get right, so nailing it down early in an easier chip is good.
