摘要:
Disclosed herein is an SRAM-compatible memory for correcting invalid output data using parity and a method of driving the same. In the SRAM-compatible memory, input data and a parity value obtained from the input data are written in data banks and parity bank, respectively. When invalid data is output from a specific memory bank due to the performance of a refresh operation or other factors, the invalid data are corrected by a data corrector using the parity value written in the parity bank, thus generating output data having the same logic value as the input data. The SRAM-compatible memory prevents a reduction in operation speed due to an internal operation, such as a refresh operation.

Disclosed herein is a synchronous SRAM-compatible memory using DRAM cells. In the synchronous SRAM-compatible memory of the present invention, a refresh operation is controlled in response to a refresh clock signal having a period “n” times a period of a reference clock signal. The refresh operation is performed while a chip enable signal/CS is inactivated. A writing/reading access operation is performed in response to a writing/reading command generated while the chip enable signal/CS is activated. Therefore, in the writing/reading access operation of the synchronous SRAM-compatible memory of the present invention, no delay of time occurs that would otherwise occur due to the refresh operation of the DRAM cells.

Disclosed herein are an SRAM-compatible memory and method of driving the SRAM-compatible memory. The SRAM-compatible memory has memory banks, a parity generator and a parity bank. The memory banks each store corresponding one of input data in its DRAM cells specified by an input address. The memory banks perform write operations independently such that when a refresh operation or a write operation for a previous frame is being performed with respect to DRAM cells of a certain memory bank, the write operation of the input data is independently performed with respect to the respective memory banks except for the certain memory bank. The parity generator generates a input parity determined based on the input data and a certain preset parity value. The parity bank stores the input parity.

The synchronous SRAM-compatible memory includes a DRAM array, a data input/output unit, an address input unit, a burst address generating unit, a state control unit, a refresh timer, and a refresh control unit. The data input/output unit controls input and output of data. The address input unit inputs a row address and a column address. The burst address generating unit generates a sequentially varying burst address. The state control unit generates a burst enable signal that enables the burst address generating unit, controls the data input/output unit, and generates a wait indication signal while an access operation of a previous frame is performed with respect to the memory array. The refresh timer generates a refresh request signal activated at regular intervals. The refresh control unit controls the refresh operation with respect to the DRAM array in response to the refresh request signal.

Disclosed herein is a method for displaying information about the use of a hack tool in the online game. When a game IDentification (ID) is input, a client system accesses a security server, and requests and receives the number of times that one or more hack tools have been used for the game ID. The client system provides the game ID and the number of times that hack tools have been used to a game server so that the number of times that hack tools have been used is shared by one or more gamers who participate in the game provided by the game server. When the client system detects the use of a hack tool, the client system increases the number of times that hack tools have been used for the game ID by 1, and provides the number of times that hack tools have been used to the security server.

Disclosed are a washing machine and a method of controlling spin-drying of the washing machine. The method changes the acceleration gradient of the drum passing a resonance point, i.e., the resonance point passing gradient of the drum, when the imbalance of the laundry due to the excessive vibration of the tub is sensed when passing a resonance point region (generally within 100 RPM, approximately 50˜80 RPM, after the entry into the spin-drying cycle) in the spin-drying cycle. Thus the position of the balancer is changed according to the imbalance of the laundry.
