    • In one aspect, a memory device includes a memory cell array, parallel internal data paths which transmit internal data to and from the memory cell array, a data driver which transmits and receives external data, and a data buffer which delays and transfers the external data received by the data driver to the internal data paths, and which delays and transfers the internal data transmitted from the memory cell array to the data driver. The memory device further includes an error correction code generator which generates an error correction code (EC) based on the internal data transmitted on the internal data paths, an EC buffer which delays the error correction code generated by the error correction code generator, an EC driver which transmits the error correction codes delayed by the EC buffer, and a latency controller which variably controls a delay time of at least one of the data buffer and the EC buffer.

    • Provided are a digital phase interpolator, which performs linear phase interpolation irrelevantly to input order of two input signals, and a semi-digital delay locked loop (DLL), which includes and controls the same. The phase interpolator includes: a first clocked inverter controlled by a phase indicating signal and providing a first output signal to a common output terminal by inverting a first input signal, and a second clocked inverter controlled by the phase indicating signal and providing a second output signal to the common output terminal by inverting the second input signal. The second clocked inverter is clocked by the first input signal when the phase indicating signal is in a first logic state, and the first clocked inverter is clocked by the second input signal when the phase indicating signal is in a second logic state. The phase indicating signal indicates a lead/lag phase relationship between the first and second input signals and is generated in a controller of a circuit of the semi-digital DLL.

    • An input/output (IO) interface includes a data encoder which encodes each of a plurality of pieces of parallel data having different timings and generates a plurality of pieces of encoded data, and an alternating current (AC) coupling transmission unit which transmits the plurality of encoded data in an AC coupling method. The data encoder compares first parallel data with second parallel data from among the plurality of pieces of parallel data on a bit-by-bit basis and obtains the number of bits whose logic states have transited between the first parallel data and the second parallel data. When the number of bits whose logic states have transited is greater than or equal to a reference number of bits, the data encoder inverts bit values of the second parallel data to generate the encoded data. When the number of bits whose logic states have transited is less than the reference number of bits, the data encoder maintains the bit values of the second parallel data to generate the encoded data.
    • 输入/输出(IO)接口包括数据编码器,其对具有不同定时的多个并行数据中的每一个进行编码并生成多个编码数据;以及交流(AC)耦合传输单元,其传输多个 的交流耦合方法中的编码数据。 数据编码器在逐位的基础上将第一并行数据与多条并行数据中的第二并行数据进行比较,并且获得其逻辑状态已经在第一并行数据和第二并行数据之间转移的位数。 当逻辑状态已经转移的位数大于或等于参考位数时,数据编码器反转第二并行数据的位值,以产生编码数据。 当逻辑状态已经转移的位数小于参考位数时,数据编码器维持第二并行数据的位值以产生编码数据。
