The memory cycle time for a 70 / 15 was 2 microseconds per byte of information.
4.
The calculation of a physical address resulted in no appreciable delay in the effective memory cycle time.
5.
In the 160 and 160-A, the memory cycle time was 6.4 microseconds.
6.
The memory cycle time was 1.44 microseconds to access two bytes ( one half word ) of information.
7.
Core memory cycle times were 20 microseconds for the Model II ( about a thousand times slower than typical computer main memory in 2006 ).
8.
Memory cycle time was halved compared to the Model I's ( internal or 1623 memory unit ), to 10 kHz ) by using faster cores.
9.
Some designs had substantially higher performance : the CDC 6600 had a memory cycle time of 1.0 �s in 1964, using cores that required a half-select current of 200 mA . Everything possible was done in order to decrease access times and increase data rates ( bandwidth ), including the simultaneous use of multiple grids of core, each storing one bit of a data word.
