Abstract	Data compression and decompression are essential in order to reduce the resources that required during transmitting and receiving data and some applications where the deviations from could be deleterious. LZW is an universal lossless technique that provides high efficiency for text as well as image data and is one of the most famous dictionary-based algorithm. Here, the designed dictionary is based on content addressable memory (CAM) array. The code for each character is available in the dictionary which utilizes less number of bits (5 bits) than its ASCII code. However, LZW technique is chosen to implement from the set of lossless methods such that it can reduce the irrelevant and redundancy of data in order to be able to transmit in efficient form and also to increase the speed of transmission. The main contribution of this work is to present a hardware LZW data compression and decompression in which LZW compression& decompression algorithms are implemented, thus the text data can be effectively compressed and recovered more efficiently which is same as that of input data.
