17 / 110 page ![]() M58LR128KT, M58LR128KB, M58LR256KT, M58LR256KB Bus operations 17/111 3.5 Standby Standby disables most of the internal circuitry allowing a substantial reduction of the current consumption. The memory is in standby when Chip Enable and Reset are at VIH. The power consumption is reduced to the standby level IDD3 and the outputs are set to high impedance, independently from the Output Enable or Write Enable inputs. If Chip Enable switches to VIH during a program or erase operation, the device enters standby mode when finished. 3.6 Reset During reset mode the memory is deselected and the outputs are high impedance. The memory is in reset mode when Reset is at VIL. The power consumption is reduced to the reset level, independently from the Chip Enable, Output Enable or Write Enable inputs. If Reset is pulled to VSS during a program or erase, this operation is aborted and the memory content is no longer valid. Table 4. Bus operations(1) 1.
