Shares of Micron (MU) - Get Report are up 2.75% in early Tuesday trading, thanks to positive commentary from analysts at Morgan Stanley.

There has been concern among investors about DRAM pricing, TheStreet's Jim Cramer, manager of the Action Alerts PLUS portfolio, said on CNBC's "Mad Dash" segment.

DRAM pricing impacts shares of Micron. As DRAM pricing goes up, profitability and margins go up for Micron and vice versa. The analysts at Morgan Stanley say the stock can go higher based on robust DRAM pricing, Cramer noted.

In essence, they don't see DRAM prices rolling over, simultaneously crushing the stock price.

"I like this call," Cramer reasoned. Because of the sophistication of these chips, factories simply can't be built overnight. They take time to build and that's why supply hasn't come online as fast as some had expected.

On the downside though, when additional supply does come online, it will likely hurt shares of Micron, he concluded.
