Title: Alan Kotok: Innovator in Memory Technology
Introduction
Alan Kotok is a notable inventor based in Waltham, MA (US), recognized for his contributions to memory technology. He holds a total of 4 patents, showcasing his innovative spirit and technical expertise in the field of data processing systems.
Latest Patents
Kotok's latest patents include a self-timed random access memory chip and a central processor with apparatus for extended virtual addressing. The self-timed random access memory chip is designed on a single monolithic integrated circuit chip. This chip includes a random access memory with addressable storage locations, address decoding circuitry, data input and output circuitry, and write enable circuitry. Additionally, it features input latches connected to chip input terminals that store data, address, and operation control signals from off-chip circuitry in response to a timing signal. The output latch on the chip stores data from the random access memory for transmission to output terminals, allowing for a pipelined operation. The chip also generates control signals in response to the latched control signals, simplifying the design process for system designers.
The central processor patent addresses a substantially larger virtual memory than the address space defined by the memory address field in an instruction. It allows for information identifying an extended address to be placed in working registers of the central processor. The processor can perform several levels of indirection based on the characteristics of each preceding indirect word, enhancing its capability to manage memory efficiently.
