I see several errors after I enable module.
To enable it, I just add this lines to the settings.php:

$settings['memcache']['servers'] = ['127.0.0.1:11211' => 'default'];
$settings['memcache']['bins'] = ['default' => 'default'];
$settings['memcache']['key_prefix'] = 'd8';
$settings['cache']['default'] = 'cache.backend.memcache';

The errors I see:

Catchable fatal error: Argument 2 passed to Drupal\Core\Cache\DatabaseCacheTagsChecksum::isValid() must be of the type array, null given, called in /modules/contrib/memcache/src/MemcacheBackend.php on line 168 and defined in /core/lib/Drupal/Core/Cache/DatabaseCacheTagsChecksum.php on line 97

The patch in the linked issue did not resolve this issue for me:

PHP Catchable fatal error: Argument 2 passed to Drupal\\memcache\\MemcacheBackend::valid() must be an instance of stdClass, null given

Ah, I see that my error is slightly different; it says stdClass, not Array.

Which version or commit of the module are you using?

I've the same error as @dagomar, I'm using the latest dev of memcache on Drupal 8.1.1.
The patch attached checks for return values of getMulti to see if it's non NULL and it works for me.

This is a duplicate of #2674884: Array exception and notices, and I actually like the way the patch is built on the other one. (testing for is_object($result) instead of simply $result).. The check in #9 succeeds if $result = 1 or TRUE or simply not empty.
