Abstract
A solid state data recorder employs a solid state memory to record data in the form of data words of variable length transmitted to the memory on a flexible width data bus. The memory is monitored to determine failed memory locations, and such locations are mapped out so as not to be used to store data. Bus lines are selected lines in accordance with mapped out memory locations in order to transfer the variable length data words to and from the memory. By employing the variable length data words and flexible width data bus, loss of useable recording space in the memory is very gradual, thus minimizing the amount of spare memory area required.
