| 20090106486 | EFFICIENT PREFETCHING AND ASYNCHRONOUS WRITING FOR FLASH MEMORY - Disclosed herein are a flash file system and an address translation method. The flash file system includes a file system, a Flash Translation Layer (FTL), and flash memory. The FTL receives Local Block Addresses (LBAs) from the file system, and translates the LBAs into Physical Block Address (PBAs. The flash memory receives the resulting PBAs. The FTL includes a memory block in which a multi-stage clustered hash table for mapping the LBAs to the PBAs is stored, and performs the address translation using the clustered hash table. | 04-23-2009 |
| 20090278588 | LOW VOLTAGE MIXER WITH IMPROVED GAIN AND LINEARITY - A frequency mixing apparatus with improved voltage gain and linearity is provided. The frequency mixing apparatus includes a transconductor, a separator, and a switching unit. A voltage gain of the transconductor is controllable, and the transconductor converts a Radio Frequency (RF) signal into a current signal under control of a self bias. The separator transfers the current signal to the switching unit. The switching unit outputs a signal having a frequency corresponding to one of a sum and a difference of a frequency of the RF signal and a frequency of a Local Oscillation (LO) signal by performing a switching operation according to the LO signal. | 11-12-2009 |
| 20100088151 | METHOD AND APPARATUS FOR RECOMMENDING IMAGE BASED ON USER PROFILE USING FEATURE-BASED COLLABORATIVE FILTERING TO RESOLVE NEW ITEM RECOMMENDATION - Provided are a method and apparatus for recommending an image based on a user profile using feature-based collaborative filtering. To generate the user profile, a model may be build from a customer purchase list database for each predetermined time. A multimedia image may be recommended, in which a purchase likeness score of a target user is high or at a predetermined level, by using the built model. | 04-08-2010 |
