memory_limit decreasing my php.ini

Plugin Name: All-in-One Event Calendar by Timely
Version: 1.10.9-standard

Hello,
this plugin is decreasing my php.ini settings.

I put in my php.ini: memory_limit = 400M, because I need it.
But when this plugin is actived, in line 12 of all-in-one-event-calendar.php file, has a code:

@ini_set( 'memory_limit', '256M' );

So, it is decreasing my default value.

I think it’s necessary use it:

$memory_limit = intval(ini_get('memory_limit'));
if ($memory_limit < 256) @ini_set('memory_limit', '256M');
