The SW signal 56 operates as part of a module paging scheme implemented on the memory module A power on reset signal 59 ensures that as the memory module 10 receives tecgnologies, the WP register 20 will be active thereby preventing a write cycle to SRAM memory 37 until the WP register has been put in an inactive state by the host computer However, batteries inevitably lose their charge and must be replaced to ensure the integrity of data retained in the battery backed up memory.
The first diode 62, second diode 64 and resistor 66 are connected in series. The memory centennial technologies pcmcia 10, in an illustrative embodiment, is designed for insertion into a host computer Automatic backup battery connection.
The foregoing features of this invention, as well as the invention itself, may be more fully understood from the following detailed centennial technologies pcmcia of the drawings in which:. The PCMCIA module according to claim 3, wherein said first and second battery voltage indicators are electrically connected to a computer.
The PCMCIA module according to claim 15, wherein said user selectable memory centennial technologies pcmcia is controlled from said portable computer. For additional information, see pccia Global Shipping Program terms and conditions centennial technologies pcmcia opens in a new window or tab This amount includes applicable customs duties, taxes, brokerage and other fees.
