PDO Exception error

Does anyone know why I keep getting this error when I add the following to my settings.php:

$conf['cache_backends'][] = 'sites/all/modules/memcache/memcache.inc';
$conf['cache_default_class'] = 'MemCacheDrupal';
$conf['cache_class_cache_form'] = 'DrupalDatabaseCache';
$conf['page_cache_without_database'] = TRUE;
$conf['page_cache_invoke_hooks'] = FALSE;

This is the error I get:

PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table '[DATABASE NAME].field_data_field_sku' doesn't exist: SELECT t.* FROM {field_data_field_sku} t WHERE (entity_type = :db_condition_placeholder_0) AND (entity_id IN (:db_condition_placeholder_1)) AND (language IN (:db_condition_placeholder_2)) AND (deleted = :db_condition_placeholder_3) ORDER BY delta ASC; Array ( [:db_condition_placeholder_0] => node [:db_condition_placeholder_1] => 565 [:db_condition_placeholder_2] => und [:db_condition_placeholder_3] => 0 ) in field_sql_storage_field_storage_load() (line 412 of /usr/www/users/[USER NAME]/modules/field/modules/field_sql_storage/field_sql_storage.module).

There is no css being picked up by the page, but the memcache stats do show underneath this error.

Thanks!
