Algebra, VIII, p. 9, § 1. Artinian Modules and Noetherian Modules

Let A be a commutative ring.

a) Let M be a Noetherian A-module. The ring AMA_M is Noetherian.

b) Let M be an A-module of finite length. The ring AMA_M is Artinian.

Let M be an A-module. Under the assumptions of a) or b), the A-module M is finitely generated. Since A is commutative, AMA_M is contained in the ring EndA_A(M), so that the countermodule of M is finitely generated. It then suffices to apply Proposition 6.

Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
