A random access memory circuit comprises a plurality of memory cells and at least
one decoder coupled to the memory cells, the decoder being configurable for receiving
an input address and for accessing one or more of the memory cells in response
thereto. The random access memory circuit further comprises a plurality of sense
amplifiers operatively coupled to the memory cells, the sense amplifiers being
configurable for determining a logical state of one or more of the memory cells.
A controller coupled to at least a portion of the sense amplifiers is configurable
for selectively operating in at least one of a first mode and a second mode. In
the first mode of operation, the controller enables one of the sense amplifiers
corresponding to the input address and disables the sense amplifiers not corresponding
to the input address. In the second mode of operation, the controller enables substantially
all of the sense amplifiers. The memory circuit advantageously provides an adaptable
latency by controlling the mode of operation of the circuit.
