"They're very strong in memory. Didn't do very much in microprocessors or digital signal processing"

Jack Kilby's quote is describing the strength of memory in microprocessors and digital signal processing. He is recommending that memory is a strong component of these technologies, however that they do not do very much in regards to microprocessors or digital signal processing. This might be analyzed as a criticism of the current state of these innovations, as he is indicating that they are not as advanced as they could be. It might likewise be interpreted as a call to action, as he is suggesting that more work needs to be done in order to enhance these technologies. In either case, it is clear that Jack Kilby thinks that memory is an important component of microprocessors and digital signal processing, which more work requires to be done in order to make them more effective.
