摘要： Provided are a cache memory using a linear hash function and a method of operating the same. The cache memory includes: a first hash function module for converting a main memory address received from a central processing unit (CPU) into a first index value using a first hash function; a second hash function module for converting the main memory address into a second index value using a second hash function; a first comparator for comparing a tag value of a data block located at the first index value in the first bank with a tag value of the main memory address; and a second comparator for comparing a tag value of a data block located at the second index value in the second bank with the tag value of the main memory address. In a pair of linear hash functions according to the present invention, each constructed with a 2m×m binary matrix, even if m is an odd number, each of the linear hash functions has the highest degree of interbank dispersion and avoids conflicts in row, column, diagonal, anti-diagonal, and rectangular patterns, so that a 2-way skewed associative cache can be constructed in relatively wide ranges.

摘要： Provided are a method of generating a Message Authentication Code (MAC) using a stream cipher, and authentication/encryption and authentication/decryption methods using a stream cipher.According to the methods, authentication/encryption is performed using a MAC generated using a stream cipher as an initialization vector of the stream cipher. Therefore, it is unnecessary to use a random number generation algorithm to generate the initialization vector, and thus implementation efficiency can be improved.In addition, upon generation of a MAC, a plurality of key stream generators perform computation for a plurality of message blocks, respectively. Therefore, the message blocks are computed in parallel at a time, and thus computation efficiency is excellent.

摘要： A computer system controlling a memory clock signal of a DIMM (dual in-line memory module) socket is described and which includes a processor controlling a 66 MHz or a 100 MHz system bus clock signal to be generated, a DIMM memory module supporting the 66 MHz or the 100 MH system bus clock signal, a clock generator generating the 66 MHz or the 100 MHz system bus clock signal by receiving control of the processor, a clock buffer, a first and a second system controllers. The clock generator and the clock buffer store setting data according to memory data of a memory module from a first system controller. The first and the second system controllers control a memory bus clock signal corresponding to an inserted single-sided type or double-sided type DIMM memory module to be outputted. As a result, a clock signal is cut off to an unused memory “model” module socket or an unused clock signal of a using memory module socket is cut off in response to “kind of an inserted” insertion of a memory module.

摘要： A method for preparing a sample for its optical analysis in the manufacture of a semiconductor device includes the step of drying a liquid formed on the semiconductor wafer until the concentration of contaminants contained in the liquid is of a sufficiently high level for the optical analyzer to adequately detect the contaminants. The liquid may be of a film formed on the wafer and dissolved into liquid drops, or deionized water or various chemicals to which the wafer is exposed during a manufacturing process. The apparatus includes a chuck for bringing the wafer into and out of a processing chamber, a guide for guiding the chuck, a piston cylinder for driving the chuck along the guide to a processing position, and a gas supplying system which directs nitrogen gas onto the wafer for drying the liquid. Appropriate controls are provided so that the apparatus can be operated automatically or manually.
