IPC: G11C11/16
Filed: 2004-07-15
Abstract: A write driver (36) uses a reference current (102) that is reflected to a driver circuit (114) by a voltage. The driver circuit (114) is sized in relation to the device (104) that provides the voltage so that the current through the driver (114) is a predetermined multiple of the reference current (102). This voltage is coupled to the driver circuit (114) through a switch (110). The switch (110) is controlled so that the driver circuit (114) only receives the voltage when the write line (52) is to have write current through it as determined by a decoder (22) responsive to an address. The driver (114) is affirmatively disabled when the write line (52) is intended to not have current passing through it. As an enhancement to overcome ground bounce due to high currents, the input to the driver can be capacitively coupled (120) to the ground terminal that experiences such bounce. Additional enhancements provide benefits in amplitude and edge rate control.
