A revised model of the Vita was released in Japan on October 10, 2013, in Europe on February 7, 2014 and in North America on May 6, 2014. The revised model, officially called the PCH-2000 series and commonly referred to as the PS Vita Slim, is 20 % thinner and 15 % lighter compared to the original model. While it largely maintains the original's overall structure and layout, the original's OLED screen has been replaced with a lower-cost LCD display. The model also roughly added about an extra hour of battery life. The newer model also comes with 1 GB of internal storage memory, although it is not possible to use both the internal memory and memory card concurrently. Upon inserting a PS Vita memory card, the system will offer to copy the existing data from the internal memory to the new card. This model has a micro USB Type B port, which can be used to charge the device along with any standard micro USB cable. The model was released in six colors in Japan (white, black, light blue, lime green, pink, and khaki), although it was only released in black and light blue in North America and Europe.
