A decoder, a method of decoding and systems implementing the same are disclosed. In one example, the method includes calculating syndrome values from input codewords, generating an error location polynomial about the codewords using the syndrome values, determining an error count in the codewords using the error location polynomial, and adjusting power consumption of a circuit in response to the determined error count in the codewords. In one example, a frequency of a clock signal to be provided to a search circuit may be determined based on the error count, and the clock signal may be provided having the determined frequency to a search circuit, such as a Chien search circuit.

A memory controller may include a cell state generator that is configured to generate a cell state for each of a plurality of multi-level cells included in a non-volatile memory device, using data of pages. The memory controller may also include a pseudo-random number generator that is configured to generate a pseudo-random number. The memory controller may further include an operator that is configured to change the cell state of each multi-level cell using the pseudo-random number, and that is configured to output a changed cell state for each multi-level cell.

A method for operating a memory controller is provided. The method includes generating a pseudo random number by using a seed included in a stored seed group corresponding to a page to be currently programmed, wherein the stored seed group is stored among a plurality of seed groups. Data to be programmed into the current page is randomizing by using the pseudo random number and the memory controller outputs the randomized data. A solid state drive (SSD) or other memory storage device such as a memory card includes the memory controller and includes a read only memory (ROM) storing the plurality of seed groups. The memory controller includes a micro-processor and a read only memory (ROM) storing executable code for causing the micro-processor to access the plurality of stored seed groups and to select a seed therefrom corresponding to a page to be currently programmed.

A method of generating interrupts and a network interface card, which minimizes the number of times that interrupts are generated, are provided. The method includes receiving data frames; estimating a first and second time delay and counting a number of received data frames; determining whether the first time delay has passed and generating an interrupt if the time reaches the first delay time, counting the number of data frames if the first time delay has not passed and generating the interrupt if the number of data frames is equal to N; determining whether the second time delay has passed if the number of data frames is not equal to N and generating the interrupt if the second time delay has passed; stopping operations of estimating the first and second time delays and counting the number of data frames in response to the interrupt generated, and transmitting the received data frames.
