The memory region included in each of the second, third and fourth semiconductor CHIPs CHIP2, CHIP3 and CHIP4 may be implemented to perform substantially the same operation as the first memory region 140 and the second memory region 150 shown in fig. 5 and 6. Therefore, a description of a memory region included in each of the second, third, and fourth semiconductor CHIPs CHIP2, CHIP3, and CHIP4 will be omitted hereinafter.

A stacked structure of the first semiconductor CHIP1 and the second semiconductor CHIP2 included in the semiconductor package 1 of fig. 1 will be described below with reference to fig. 7.

The first semiconductor CHIP1 may be stacked on the substrate SUB such that the first pad region 110 is located at an upper edge region of the first semiconductor CHIP1 in a plan view, and the second pad region 120 is located at a right edge region of the first semiconductor CHIP1 in a plan view.

The second semiconductor CHIP2 may be stacked on the first semiconductor CHIP1 such that the third pad region 210 is located at a lower edge region of the second semiconductor CHIP2 in a plan view and the fourth pad region 220 is located at a left edge region of the second semiconductor CHIP2 in a plan view. In this case, the second semiconductor CHIP2 may be laterally offset with respect to the first semiconductor CHIP1 to expose the first and second pad regions 110 and 120. Accordingly, the first and third pad regions 110 and 210 may be point-symmetrical with respect to center points of the first and second semiconductor CHIPs CHIP1 and CHIP2 when viewed from a plan view. Similarly, the second and fourth pad regions 120 and 220 may also be point-symmetric with respect to the center points of the first and second semiconductor CHIPs CHIP1 and CHIP2 when viewed from a plan view.

As described above, the second semiconductor CHIP2 may be stacked on the first semiconductor CHIP1 so as to be laterally offset in a first direction (i.e., a first lateral direction). In this case, although not shown in fig. 7, the third semiconductor CHIP3 may be stacked on the second semiconductor CHIP2 to be laterally offset in a second direction (i.e., a second lateral direction) opposite to the first direction, such that the third and fourth pad regions 210 and 220 are exposed. That is, the second, third, and fourth semiconductor CHIPs CHIP2, CHIP3, and CHIP4 may be vertically stacked on the first semiconductor CHIP1 in a zigzag manner to expose their pad regions and provide a space sufficient to bond the wires W1 to W4 to the pads P1 to P4, even though any intermediate layered elements disposed between the first to fourth semiconductor CHIPs CHIP1, CHIP2, CHIP3, and CHIP4 are not used. As a result, the total thickness of the semiconductor package 1 can be reduced.

The semiconductor package 1 described with reference to fig. 2 to 7 may be applied to electronic systems including a memory system, a graphic system, a computing system, a mobile system, and the like. For example, as shown in FIG. 8, an electronic system 1000 according to an embodiment may include a data storage circuit 1001, a memory controller 1002, a buffer memory 1003, and an input/output (I/O) interface 1004.

The data storage circuit 1001 may store data output from the memory controller 1002, or may read and output the stored data to the memory controller 1002 according to a control signal output from the memory controller 1002. The data storage circuit 1001 may include a nonvolatile memory that retains their stored data even when power supply thereto is interrupted. The nonvolatile memory may be a flash memory such as a NOR type flash memory or a NAND type flash memory, a phase change random access memory (PRAM), a Resistive Random Access Memory (RRAM), a Spin Transfer Torque Random Access Memory (STTRAM), a Magnetic Random Access Memory (MRAM), or the like.

The memory controller 1002 may receive a command output from an external device (e.g., a host device) through the I/O interface 1004 and may decode the command output from the host device to control an operation for inputting data into the data storage circuit 1001 or the buffer memory 1003 or for outputting data stored in the data storage circuit 1001 or the buffer memory 1003. Although fig. 8 shows the memory controller 1002 having a single block, the memory controller 1002 may include one controller for controlling the data storage circuit 1001 and another controller for controlling the buffer memory 1003 composed of a volatile memory.

The buffer memory 1003 may temporarily store data to be processed by the memory controller 1002. That is, the buffer memory 1003 can temporarily store data output from or input to the data storage circuit 1001. The memory 1003 may store data output from the memory controller 1002 according to the control signal. The buffer memory 1003 may read and output the stored data to the memory controller 1002. The buffer memory 1003 may include the semiconductor package 1 shown in fig. 2. The buffer memory 1003 may include a volatile memory such as a Dynamic Random Access Memory (DRAM), a mobile DRAM, or a Static Random Access Memory (SRAM).

The I/O interface 1004 may physically and electrically connect the memory controller 1002 to an external device (i.e., a host). Accordingly, the memory controller 1002 may receive control signals and data provided from an external device (i.e., a host) through the I/O interface 1004 and may output data output from the memory controller 1002 to the external device (i.e., the host). That is, electronic system 1000 may communicate with a host through I/O interfaces 1004. The I/O interface 1004 may include any of a variety of interface protocols, such as Universal Serial Bus (USB), Multi-media card (MMC), peripheral component interconnect express (PCI-E), Serial Attached SCSI (SAS), Serial AT attachment (SATA), parallel AT attachment (PATA), Small Computer System Interface (SCSI), Enhanced Small Device Interface (ESDI), and Integrated Drive Electronics (IDE).

Electronic system 1000 may be used as a secondary storage device to a host or an external storage device. The electronic system 1000 may include a Solid State Disk (SSD), a USB memory, a Secure Digital (SD) card, a mini secure digital (mSD) card, a micro secure digital (micro SD) card, a Secure Digital High Capacity (SDHC) card, a memory stick card, a Smart Media (SM) card, a multimedia card (MMC), an embedded multimedia card (eMMC), a Compact Flash (CF) card, and the like.
