        if ($this->_itemsPerPage === null) {

            $memoryLimit = trim(ini_get('memory_limit'));

            $lastMemoryLimitLetter = strtolower($memoryLimit[strlen($memoryLimit) - 1]);

            switch ($lastMemoryLimitLetter) {

            case 'g':

                $memoryLimit *= 1024;

            // fall-through intentional

            case 'm':

                $memoryLimit *= 1024;

            // fall-through intentional

            case 'k':

                $memoryLimit *= 1024;

                break;

            default:

                // minimum memory required by Magento

                $memoryLimit = 250000000;

            }
