Abstract
A data storage device is configured to store a database of objects in an NVM die as binary vectors and to then search the database based on binary key vectors. The binary vectors may be received from a host for storage in the NVM die. In other examples, a data storage controller converts floating-point vectors received from the host into binary vectors for storage in the NVM die. Various procedures are described for converting the floating-point vectors into binary vectors. Exemplary procedures are also described for comparing a binary key vector received from the host with the binary vectors stored in the NVM die to detect matches. For example, a sequence of commands is described for applying by the data storage controller to the NVM die to control the die to identify and count matching bits using the latches of the NVM die. Volatile memory implementations are also described.
