Abstract: A data storage device is provided. The data storage device includes: a flash memory, a dynamic random-access memory (DRAM), and a controller. The flash memory includes a plurality of physical blocks for storing data. The controller is configured to allocate a cache space from the DRAM according to at least one data feature of a write command from a host. The controller writes first data indicated by the write command into the cache space. In response to receiving a read command from the host, the controller determines whether the cache space contains all of the second data indicated by the read command. When the cache space contains all of the second data indicated by the read command, the controller retrieves the second data indicated by the read command directly from the cache space.

Abstract: A touch display panel includes first and second substrates opposite to each other, wherein a surface of the first substrate distal to the second substrate is a light exit surface including a display region and a peripheral region; a first driver provided at a first side of the peripheral region; and a second driver provided at a second side of the second substrate, wherein the first and second sides overlap each other in a stacking direction of the first and second substrates. An extension region, along a lengthwise direction of the second side, of an orthographic projection of the first driver on the second substrate is a first extension region, an extension region, along the lengthwise direction, of a region of the second substrate occupied by the second driver is a second extension region, and the first and second extension regions at least partially overlap each other.
