Let $R$ be a ring with unity such that both $R/Soc(R_R)$ and the full matrix ring $M_n(R/Soc(R_R))$ are both Boolean rings ($n> 1)$. Is it true that $R$ is semisimple?
For semisimple rings the answer is obviously in affirmative, since in this case we have $R=Soc(R_R)$, and both rings are zero.
Thanks for any suggestion/help!
