Extensive Memory Technology

Extensive Memory Technology or eXm refers to the technology of extracting, digitally storing and replaying memories from the human brain. Electromagnetic radiation in the microwave range can detect the firing of individual neurons in the Hippocampus during the process of storing present experiences as future conscious recollections. The device can then retransmit this stored ‘memory’ back into the neurons via synaptic transmission. The recipient experiences the recorded sensory experience as though it is happening to them. Memories may be stored and distributed digitally and replayed by others with a device enabled with eXm, such as a smart phone.


eXm was developed by Dr. Elizabeth Evans, a professor of Quantum Chemistry at Nottingham University and exploits the formerly theoretical concept that sub-atomic particles called bosons operate in multiple dimensions. The microwave transmitter/receiver of the smartphone is used to transmit and extract differential form generalisations of the vector potential electromagnetic field.

Sale to Mevokia

After failing at secure significant development funding Dr. Evans sold the intellectual property of the concept to the South Korean telco Mevokia Corporation. Despite vigourously protecting their exclusive license to the technology there are many copies and fakes available.


In 2013 the UK Government rushed through legislation to legalise memory exchange and sold the rights to exploit eXm technology in the UK to Mevokia Corporation for £22 billion. The XM, a UK based lobbying group, has alleged that bribes were paid to Government ministers.

Economic value

The recording, distribution, exchange and play-back of extensive memory recordings was made illegal in many territories including the UK (in 2008) after several high profile incidents of severe mental and psychological damage caused by the exchange of memories. In South Korea, where memory exchange was legalised in 2009, 43 percent of the adult population now have memory enabled handsets and “jack in” to memories at least once a day. It is worth more to the Korean economy than the computer games industry. Mevokia has successfully lobbied several national governments to legalise the technology and grant them an exclusive licence. Belgium, Brasil and Vietnam legalised in 2010, The UK is due to legalise in May 2013.


The Royal Society of Psychotherapists has stated it’s opposition to legalisation and cites several studies that show the experiencing of other’s memories can cause lasting psychological harm.
