Question: Warrendale and The Memory of Justice, are which type of films?

Context paragraphs:
Concurrent overlap: In human memory research, concurrent overlap, or task appropriate processing, is a type of processing overlap between an activity engaged in before the prospective memory is to be remembered and a cue that directs attention towards the prospective memory.  It is prospective memory specific and is distinct from sequential overlap, or transfer-appropriate processing, which occurs in both retrospective and prospective memory and is defined as the overlap in processing the to-be-remembered memory between planning (or study in retrospective memory) and test times.

Memory leak: In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations in such a way that memory which is no longer needed is not released.  In object-oriented programming, a memory leak may happen when an object is stored in memory but cannot be accessed by the running code.  A memory leak has symptoms similar to a number of other problems and generally can only be diagnosed by a programmer with access to the program's source code.

Dynamic random-access memory: Dynamic random-access memory (DRAM) is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit.  The capacitor can be either charged or discharged; these two states are taken to represent the two values of a bit, conventionally called 0 and 1.  Since even "nonconducting" transistors always leak a small amount, the capacitors will slowly discharge, and the information eventually fades unless the capacitor charge is refreshed periodically.  Because of this refresh requirement, it is a "dynamic" memory as opposed to static random-access memory (SRAM) and other "static" types of memory.  Unlike flash memory, DRAM is volatile memory (vs. non-volatile memory), since it loses its data quickly when power is removed.  However, DRAM does exhibit limited data remanence.

T-RAM: Thyristor RAM (T-RAM) is a new (2009) type of random-access memory invented and developed by T-RAM Semiconductor, which departs from the usual designs of memory cells, combining the strengths of the DRAM and SRAM: high density and high speed .  This technology, which exploits the electrical property known as negative differential resistance and is called thin capacitively-coupled thyristor, is used to create memory cells capable of very high packing densities.  Due to this, the memory is highly scalable, and already has a storage density that is several times higher than found in conventional six-transistor SRAM memory.  It was expected that the next generation of T-RAM memory will have the same density as DRAM .

The Memory of Justice: The Memory of Justice is a 1976 documentary film directed by Marcel Ophüls.  It explores the subject of atrocities committed in wartime and features Joan Baez, Karl Dönitz, Hermann Göring, Hans-Joachim Kulenkampff, Yehudi Menuhin, Albert Speer and Telford Taylor.

Non-volatile memory: Non-volatile memory, nonvolatile memory, NVM or non-volatile storage is a type of computer memory that can retrieve stored information even after having been power cycled (turned off and back on).  The opposite of non-volatile memory is volatile memory which needs constant power in order to prevent data from being erased.  Examples of non-volatile memory include read-only memory, flash memory, ferroelectric RAM, most types of magnetic computer storage devices (e.g. hard disk drives, solid state drives, floppy disks, and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards.

Nelson Dellis: Nelson Charles Dellis (born February 4, 1984) is a memory athlete, mnemonist, public speaker, and consultant.  He is a four-time USA Memory Champion.  He is one of the co-founders of Memory League (formerly, Extreme Memory Tournament) , a new type of competitive memory platform that allows memory enthusiasts to challenge each other online.

Read-write memory: Read-write memory is a type of computer memory that may be relatively easily written to as well as read from, that is, using electrical signalling normally associated with running software, and without other physical processes (unlike ROM or "read-only memory" and distinct from EEPROM).  The related term RAM (for "random access memory") means something different; it refers to memory that can access any memory location in a constant amount of time.

Warrendale: Warrendale is a 1967 documentary film by Canadian filmmaker Allan King.  It was originally produced for broadcast on CBC Television, but was never shown due to King's refusal to edit out the copious profanity in the footage.

Memory refresh: Memory refresh is the process of periodically reading information from an area of computer memory and immediately rewriting the read information to the same area without modification, for the purpose of preserving the information.  Memory refresh is a background maintenance process required during the operation of semiconductor dynamic random-access memory (DRAM), the most widely used type of computer memory, and in fact is the defining characteristic of this class of memory.
